installed gnome-radio extension.  Could no longer continue. When I opened the login after password, lost the mouse, keyboard and monitor.
However, a background download was operating (disk light blinking).  
Only recourse, --reboot.

I've noticed   this happens quite a bit. Typically it will happen when I'm signed into my account and have several 
applications open (on a typical day it's Rambox, Pidgin, Thunderbird, Google Chrome, and several xterms) and I lock
my screen to step away for a moment. When I come back, I go to log back in, but I'm presented with a new login that 
creates a new session. When I get logged back in, I'm given a "Gnome Crashed" notification. It's not always and not 
consistent, I don't know how to recreate the issue.

 Using btrfs makes Gnome crash on several occasions. This is a violation of default panel functionality.

-1 blocker. I don't like crashes, but this looks like the previous situation where we have a number of different bugs from different causes getting lumped into one, making it look like one big severe problem when really there are probably many different causes.

Comment 57 Adam Williamson 2017-11-09 18:10:12 UTC
Well, in this case the backtraces do look more similar to me. Several of the system logs show something like:

Jul 10 15:31:04 localhost.localdomain gnome-shell[1451]: g_value_set_object: assertion 'G_IS_OBJECT (v_object)' failed

also.

To ask some standard questions: does anyone have a reliable reproducer for this? And can affected folks say whether they have any extensions enabled?

Comment 58 Adam Williamson 2017-11-09 18:34:59 UTC
Marking as CommonBugs...note the intent here is to add an entry covering this and several other crasher bugs, noting that we aren't yet clear on precisely what circumstances are known to cause crashes, but anyone experiencing recurring crashes may wish to switch to X11 to mitigate the effect of them.

Comment 59 Jonathan Haas 2017-11-09 18:41:44 UTC
Bug 1494586 and Bug 1489554 (which are probably duplicates or related, but not sure without usable JS backtrace) seem to indicate that this is at least partially caused by shell extensions, in particular Pomodoro timer.

Comment 60 Adam Williamson 2017-11-09 20:15:41 UTC
Note that upstream decided Leslie's case was related to this extension:

https://github.com/zpydr/gnome-shell-extension-taskbar

Leslie claims it's related to multiple extensions that have settings when using btrfs, but I'm not sure that's proven.

(In reply to Fedora Blocker Bugs Application from comment #53)

I still doubt this is related to btrfs at all. I don't have any indication why any code path should be different if gnome-shell is running on a machine with btrfs.

In my case there is no pomodoro timer (and never has been).

Comment 62 Adam Williamson 2017-11-09 20:29:30 UTC
Christian: well, the factors pointing to btrfs so far are:

* Either two or three reporters mention that they use it (depends if superdanby is the same person as Leslie or 陳鐸元)
* Leslie claims that the crashes only happen when he's using btrfs; if he uses the same extensions but no btrfs, no crashes

It'd be good to have more data from more reporters, of course. *Are* you using btrfs, in point of fact?

Comment 63 Adam Williamson 2017-11-09 21:07:37 UTC
Discussed at 2017-11-09 Final Go/No-Go meeting, acting as a blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-1/2017-11-09/f27-final-and-server-beta-go-no-go-meeting.2017-11-09-18.02.html . Rejected as a blocker: we are concerned about this bug, but it was nominated too late for us to be able to be at all certain it's sufficiently severe and commonly-encountered to constitute a release blocker. We at least know it does not affect any of those in the meeting (many of whom run Shell on F27), and some reports indicate it's not specific to F27 either (it also seems to affect earlier releases).

If it does turn out to only affect systems using btrfs in combination with certain extensions, that certainly wouldn't be significant enough to qualify for blocker status.

Comment 64 Łukasz Faber 2017-11-09 21:38:23 UTC
I have never used btrfs (all of my fs are ext4) and I was experiencing this error. Currently, after disabling most of my extensions, both this one and bug 1494586 happens rarely.

Comment 65 Adam Williamson 2017-11-09 21:59:52 UTC
Lukasz: thanks. You say you disabled "most" of your extensions - which ones are still enabled? Can you run without those as well for a bit, and see if crashes still happen at all?

Yes, I am running my Fedora system on a btrfs partition.

Comment 67 Łukasz Faber 2017-11-09 23:10:34 UTC
Adam: I am currently using (as I mentioned in the other bug):
- Do not disturb button
- Kstatusnotifieritem/appindicator support
- Topicons (not Plus)
- User themes
And I didn't have a gnome-shell related crash for over a week till yesterday. When I was testing other extensions yesterday, I got the error from bug 1494586 after disabling Pomodoro and enabling Recent items. However the crash could be caused by interaction between any of these extensions, so it does not prove anything.

Before disabling other extensions bug 1494586 was happening multiple times a day and this one every few days.

If I can provide more info, please let me know.

Comment 68 Kevin Suo 2017-11-10 00:12:52 UTC
As I have said, Fresh installation of Fedora 27 beta1, then Click to open a LUKS encrypted partition in Nautilus. (for me this partition is located in a usb hard drive) will cause the crash.
I am not using btrfs. The system is installed in ext4 partition. The LUCKS partition is also ext4.

Comment 70 Debarshi Ray 2017-11-10 07:34:38 UTC
The upstream bug has a patch to fix crashes caused by setting the label on invalid StLabel objects.

Comment 71 Leslie Satenstein 2017-11-11 04:31:18 UTC
Please refer to 1464294 for similar (more detailed results of testing)

For F27 or F27 beta, I allow / to be on btrfs and /home onto ext4.
That works.

Comment 90 Kevin Suo 2017-11-28 12:36:39 UTC
Those who  are still  encountering the crash, I suggest you try to do a fresh reinstall using  the most  recent release  iso.

Previously I reproduced the crash with the beta release. Now I installed using the iso downloaded today but no longer encounter crash.

Why would a fresh reinstall be any different from an updated system? That does not make any sense to me. Maybe you just don't have the same extensions installed.

Anyway, a fix has been committed upstream 8 days ago and will land in gnome-shell 3.26.3 which has not been released yet.

Similar problem has been detected:

I don't have any step to reproduce.
The laptop was running for several days, has been suspended and restarted multiple times. I had mostly Eclipse IDE and Firefox running (both with not so many tabs), and then it froze and Fedora automatically restarted the session (I had to re-login, re-open apps...)

Similar problem has been detected:

Log in to shell session, then lock screen or close laptop lid. Wait a minute then move mouse/press a key/open lid to
wake up the device. The lock screen showed for a second, then flickered, then I was back to a log in prompt (not unlock
prompt; the button below the text field says "Sign in") and on log in, none of previously running programs were still running.

Comment 138 dizzy 2018-01-19 12:55:28 UTC
Same crashes for me - seems to have something to do with having my andorid phone plugged into USB (charge only mode). When plugged/unplugged, gnome session will most likely crash soon (usually next lock/unlock).
It is pretty annoying as I loose the whole gnome session on each crash :-(

I can confirm the fix is valid on my Fedora27 workstation.

This issue makes Fedora27 as workstation not usable.
Would you be able to proceed the backport to Fedora27 soon?

Disabling the extension:

Now works fine.

Comment 154 Adam Williamson 2018-01-27 21:44:12 UTC
Arne: Silvio: as mentioned earlier in the thread, there is an issue where some GNOME bugs are incorrectly considered duplicates. Arne, if the update fixed your crashes, you very likely *were* suffering from this issue. Silvio, if an extension is involved and this update doesn't fix your problem, you very likely are *not* suffering from this issue, but a different bug; it might be best to file a new bug, with (ideally) your traceback and at least the system logs from around the time of the crash, and we may be able to figure out what's happening to you. Thanks, and sorry for the trouble.

I suffer from the crash with this extension also, when plugin the usb or umount it from witin file manager. I noticed that when it crashes, no crash reports are generated nor reported automatically.

I see there is an update to this extension (and some others), but I am not to get updates to any of the gnome extensions from the Gnome Software or dnf.

Yes this is a different issue.

Comment 157 Silvio Marazzato 2018-01-29 12:22:18 UTC
With gnome-shell-3.26.2-4.fc27 the problem with the places-status-indicator plugging external USB storage persists. Is not possible to collect report using the Fedora 27 provided tool due to corrupted data(there is a Python3 problem).

Comment 158 fedeb1995 2018-01-29 23:17:47 UTC
I can confirm that Places Status Indicator seems to be the (or at least, a) trigger to this bug. Any filesystem mount/unmount through nautilus, gnome disks or automount makes the shell crash if said extension is active.

Comment 159 Ariel 2018-01-30 06:03:05 UTC
I can also confirm that the problem persists with 

Installed Packages
Name         : gnome-shell
Version      : 3.26.2
Release      : 4.fc27

Further, I don't have the "Places Status Indicator" extension installed and it happens anyways, usually triggered in Nautilus when "ejecting" a remote sshfs mount, not every single time but often enough to ruin the Wayland user experience and force the use of X11

Comment 160 Ariel 2018-01-30 06:39:14 UTC
p.s. I did notice that the crash triggered from a Nautilus 'eject of remote sshfs mount' tends to happen more often after a suspend/resume or hibernate/resume cycle.
