Description Amy 2015-08-22 03:59:06 UTC 
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?
Comment 2 Amy 2015-08-22 04:08:06 UTC 
It doesn't look like it. Just looked using dpkg - - get-selections | grep bleachbit
Comment 3 Bhushan Shah 2015-08-22 04:09:58 UTC 
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/
Comment 4 Giorgio 2015-08-28 16:13:11 UTC 
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:

Comment 5 Giorgio 2015-08-28 16:20:24 UTC 
I don't have bleachbit and I use mesa drivers.
Comment 6 Giorgio 2015-08-30 14:21:13 UTC 
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.

Indeed, these are not related at all, looks more like an old Qt bug showing up again, related to bug 339285
Comment 10 Myriam Schweingruber 2015-12-27 10:44:06 UTC 
*** Bug 355341 has been marked as a duplicate of this bug. ***
Comment 11 David Edmundson 2016-11-04 22:59:25 UTC 
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.
