Description Jason 2016-04-28 22:56:41 UTC 
Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Frameworks Version: 5.21.0
Operating System: Linux 4.5.0-3-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

-- Information about the crash:
I was changing virtual desktops (slide transition) when the crash occurred. It isn't 100% reproducible but it does seem to happen more when I have effects (i.e. hardware acceleration) enabled. 

Running openSUSE Tumbleweed x86_64, Plasma 5.5.3 if that isn't clear by the crash report.

The crash can be reproduced sometimes.

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