Comment 14 Jacek Chrząszcz 2015-12-18 13:30:16 UTC
Another user experienced a similar problem:

This happened (and it does happen quite often) when I tried to switch off my external monitor using (autorandr - a script based on) xrandr. Everything blows up, including the konsole I launch the command in, after some time the plasma sometimes returns (this time it did return when I issued some xrandr commands blindly), but e.g. konsoles do not.
May-be it is important that I change the --scale of my screen, i.e. I go from DP2-1@1x1+eDP1.65 to eDP1@1x1.
This blow-up happens almost every time I do that - I have to reboot after that. This happens on Lenovo T540p using a Dock, but note that I do not undock before the blow-up. This instability is frustrating...

Comment 15 MartinG 2016-01-03 15:00:07 UTC
Another user experienced a similar problem:

I pressed one of two volume tray icons, and tried to adjust the volume. plasma crashed.
I had both kmix system tray and "the other" volume system tray active. I think it was the other that made plasma crash.
I had both active, since I didn't want youtube videos to start at 100 % volume each time, and there was no "volume" plasmoid available when I searched. However, upon restart I suddenly had two.

No idea if these are related, and due to the instability of Plasma after upgrading to Fedora 23, they likely are not.

Comment 23 Jonathan Wakely 2016-02-23 10:47:21 UTC
I inserted a luks-encrypted USB drive, clicked on "Open in File Manager" when the device notification popped up, entered the passphrase for the disk, and got an error saying something like "Could not mount a disk". That was bogus, because it was showing as mounted in the device notifier. I clicked "Open in File Manager" again, and got the error again, then plasmashell crashed.

Comment 45 Reartes Guillermo 2016-05-09 19:02:03 UTC
plasmashell crashes after a dnf update, kde became UNUSABLE.
i reported it manually in BZ #1333982

i am using lxqt desktop, since kde is unusable since this friday.

today i was able to generate the backtrace for BZ #1333982, and abrt created BZ #1334498 (private dup of this one).

Comment 52 Fedora Blocker Bugs Application 2016-06-02 13:49:53 UTC
Proposed as a Freeze Exception for 24-final by Fedora user rdieter using the blocker tracking app because:

 A workaround for plasma crash issue that is unfortunately not uncommon, as can be seen by the number of duplicate reports both downstream and upstream.  Seems to affect some users more often (arguably making plasma unusable for them).

Comment 53 Adam Williamson 2016-06-03 22:45:02 UTC
+1, fixing commonly-encountered crashers on live images is a good FE justification.

Comment 54 Chris Murphy 2016-06-04 00:34:02 UTC
+1 FE, hard to imagine the fix involves a regression worse than frequent crashes, so let's fix it.

This bug was discussed at the 2016-06-06 blocker review meeting [1] and determined to be an AcceptedFreezeException as many people have experienced this and fixing it is a good idea in a release-blocking desktop.

Please not that the patch to fix the problem has changed.
There's now a workaround committed in plasma-nm and different proposed patch to Qt:
https://bugs.kde.org/show_bug.cgi?id=346118#c131
Qt correct report is:
https://bugreports.qt.io/browse/QTBUG-53677

Comment 61 Rex Dieter 2016-06-16 13:07:33 UTC
We're already including the candidate for for QTBUG-53677 in the aforementioned qt5-qtdeclarative update.

We can look into backporting the plasma-nm fix as well.

Please note that this is (always) happening to me with:
$ rpm -q qt5-qtdeclarative
qt5-qtdeclarative-5.6.0-11.fc23.x86_64
So the "try to connect to VPN / Wifi with changed MTU" problem seems to be fixed, while the "getting out of display power save" problem still leads to a crash.
