Application: plasmashell (5.9.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.1-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
From time to time Plasma crashes when I close a window. This happens once every few days. I did not find a way to reproduce it intentilly but in all cases my system (notebook) was either suspended or running idle (with sceen saver) before the crash happened.

The crash can be reproduced sometimes.

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