Description danilin22 2016-11-16 11:51:08 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
It usually happpens when I  start an application (usually by clicking  an icon on my desktop)
or just killing a windows with an appication (like midnight-commander) by clicking on the
X in the upper-right angle.  BUT: I can not reliably reproduce a crush: looks  like 
it  happens not on every kill/create event but rather once  per few  (say 5 or even 10) such
events.

The crash can be reproduced sometimes.

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