Bug 698190

Created attachment 493452 [details]
File: backtrace

Package: gnome-shell-3.0.0.2-2.fc15
Architecture: i686
OS Release: Fedora release 15 (Lovelock)


How to reproduce
-----
1. Install F15 beta packages (used preupgrade from Fedora 14)
2. Click on "Applications" in Gnome shell
3. Boom, have to logout of shell

This makes Gnome Shell completely unusable for me.

For #3 I meant, Get the sad face that fills the screen and says you have to log out.

I believe this is the problem discussed at https://admin.fedoraproject.org/updates/gnome-menus-3.0.0-2.fc15,gnome-shell-3.0.0.2-2.fc15,gnome-panel-3.0.0.1-2.fc15 , and updating to gnome-menus-3.0.0-2.fc15 should fix it.

The bug is valid and should stay open, though, as Shell should not crash hard in this case; jclinton wanted there to be a bug for this, so leaving it open but un-marking it as a blocker as you won't hit this crash with the correct gnome-menus.

walters is working on re-writing this section of the code upstream and it will be more resilient against these kinds of missing file problems as a result of the re-writing. Thank you for the backtrace!

Though if we want a quick fix, we should just return NULL in shell_app_system_get_sections() since the JS code handles a NULL return just fine in appDisplay.js.

It looks like this *may* be fixed by the most recent commit to gnome-shell.spec, which ups the gnome-menus requirement (and thus, may be fixed by updating your gnome-menus package to 3.0.0-2). But walters didn't bump the Release with that change, so the current package doesn't have that requirement.

er, wrong bug

Yes, I ran a full 'yum update' after using preupgrade and it pulled in these updates.  It works now!

Not sure what state this bug should remain or if you're planning to take in the change in comment#7

we're considering this bug to be for the crash in GNOME Shell if the file is missing, so making the file show up again doesn't close this bug.

Package: gnome-shell-3.0.0.2-2.fc15
Architecture: i686
OS Release: Fedora release 15 (Lovelock)


How to reproduce
-----
1. Login with Gnome Shell
2. Wait three seconds
3. Watch it crash and burn


Comment

I doesn't seem to matter what I attempt to do after I login, even if I do nothing at all, Gnome will crash spectacularly about 3 seconds after I've logged in.

Lana: see the discussion above, you just need to pull the latest gnome-menus to fix this.

This message is a notice that Fedora 15 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 15. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 15 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
