Application: plasmashell (5.3.2) Qt Version: 5.4.1 Operating System: Linux 3.19.0-26-generic i686 Distribution: Ubuntu 15.04 -- Information about the crash: - What I was doing when the application crashed: I was logging into KDE/Plasma, and during the loading process Plasma failed to load and gave me the crash notification. If I attempted to reload from dialog, it simply generated another crash notification. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Bus error Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Do you have bleachbit installed?
It doesn't look like it. Just looked using dpkg - - get-selections | grep bleachbit
Okay, to me it looked like well known crash due to bleachbit, thats why I asked : http://blog.martin-graesslin.com/blog/2012/07/do-not-use-bleachbit/
I experience the same problem. I have Debian sid on linux kernel 4.1.0-2 , plasma-workspace 4:5.3.2-2, qt5 5.4.2+dfsg-8. Every time I try to login in kde I have 4 windows reporting a segfault, 1 from krunner e 3 from plasmashell. -- Backtrace: Application: krunner (krunner), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I don't have bleachbit and I use mesa drivers.
My problem seems to be related to xorg that doesn't load properly glx.
#12 0x00007f91f76efc8b in QOpenGLContext::create() () from /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 Error raised here means there's something broken with your openGL drivers. There's some comments in the linked report that might help you, there's an envrionment variable to force it to use software rendering. Though generally if you have Mesa you shouldn't need this at all, and it's more a sign that some part of the setup is broken. *** This bug has been marked as a duplicate of bug 345563 ***
The backtrace in comment #0 is unrelated to bug 345563.
(In reply to Christoph Feck from comment #8) > The backtrace in comment #0 is unrelated to bug 345563. Indeed, these are not related at all, looks more like an old Qt bug showing up again, related to bug 339285
*** Bug 355341 has been marked as a duplicate of this bug. ***
This is against an old version of Qt/Plasma and there has been no update or newer duplicates. Hopefully that implies this has been fixed in the many developments that have happened in Plasma and our supporting libraries. If it still occurs please open a new bug report with a more recent backtrace.
