Description Rolf 2017-08-07 14:07:29 UTC 
Application: plasmashell (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.76-1-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:

I was closing some apps (multiple Dolphins), by right click on grouped Dolphin icon in controlbar / taskbar and selected close.
This an similar closing apps often create KWin crashes.

Note: KWin restarts itself automatically. So there are just some flickers, and the disappearance of Desktop Icons as well as controlbar / taskbar. But those re-appear after restart of KWin. (Just with additional Bug Assistant.)

The crash can be reproduced sometimes.

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