Sentry Crash Report:

Description pmanousis 2016-01-06 08:56:25 UTC

Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I just logged in and it crashed!  I am not sure if this is an error that is because of the fglrx driver or not.  Another thing I noticed is that kwin also occasionaly crashes.

The crash can be reproduced every time.

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

I thought that fglrx had to do sth with the bug and I reinstalled it. Apparently I was wrong.

Since I have set to KDE to remember my session, the next thing I did was to quit from Kontact application before logging off and on.  This made it work properly!

I suspect that since Kontact wants to use KWallet, and KWallet starts with a "pop-up" dialog to ask for the code, it makes the plasma collapse.  When I was not running Kontact and there was no KWallet, everything went smooth as expected.
