Sentry Crash Report:

Description Georg Grabler 2014-11-30 17:23:34 UTC 
Application: plasmashell ()

Qt Version: 5.3.0
Operating System: Linux 3.16.0-25-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed:
I undocked my dell e6420 (Intel HD3000) from the docking station having a Monitor attached (DVI, though, the display&monitor says it's HDMI for a yet unknown reason).
This crash happens every time I undock the laptop from the docking station, though, it resurrects itself.

- Unusual behavior I noticed:
=> The whole desktop went black.
=> A lot of flickering started.
=> The crash notice was shown.
=> Plasma restarted (I think) and the background / taskbar was displayed again.
=> some windows stay black except for the window decorations (maybe KWin related though). 100 % candidate for this is Chromium, but i had that with Konsole as well, so it seems not to be toolkit related, and I have to restart the applications since moving, resizing, minimizing/maximizing didn't seem to resurrect them.

- Special system information/configuration
I'm using kubuntu-ppa-ubuntu-next-utopic and kubuntu-ci-ubuntu-unstable-daily-utopic, on amd64.
I am using systemd and a manually (as root) started sddm on KUbuntu because sddm is compiled with -DNO_SYSTEMD, if that could cause implications. SDDM wouldn't start for me at all with upstart.


If you need any additional debug information and/or debug packages installed for the backtrace let me know (I only installed workspace for the plasmashell which actually crashed).

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Marco Martin 2014-12-02 17:32:27 UTC 
possible upstream QScreen problem?
Comment 2 Aleix Pol 2014-12-02 17:52:49 UTC 
Possibly, still we should identify it.
Comment 3 Aleix Pol 2015-01-08 16:32:53 UTC 
This is not really moving forward.

Can we get a backtrace with symbols? Maybe a way to reproduce it? I cannot anymore, this might be fixed, if it was using KScreen kded.
