Sentry Crash Report:

Description Andrew W 2015-11-12 18:09:29 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I had just logged in.  I had actually booted the machine a couple of minutes earlier and this delay could be part of the problem.
The nouveau kernel patch which fixed https://bugs.freedesktop.org/show_bug.cgi?id=92504 has *not* been applied - this is an Opensuse Leap 42.1 install with no experimental repositories included.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Reported using DrKonqi
Comment 1 Martin Klapetek 2015-11-12 18:36:42 UTC 
Thanks for the report

Is there any chance you can actually try the solution in the bug you linked?
Comment 2 Andrew W 2015-11-12 20:24:47 UTC 
- I had to kill plasmashell in order to be able to perform the kernel update.
- On a reboot (with the fix applied), plasmashell aborted again.

One previous such abort-after-a-boot was also after I had to kill plasmashell so further testing on my part required.  I could not get DrKonqui to attach the new trace to this bug report so if it happens again I will have to file a new bug and then refer to this one.
Comment 3 Andrew W 2015-11-13 19:27:01 UTC 
It has happened again, the trace is broadly similar to its predecessor.
I had closed the system down cleanly after the previous session and the nouveau patch I linked to before has been applied.  I do not have any more ideas as to what the cause could possibly be.
The system is perfectly useable even after the crash.
