Application: plasmashell (5.7.3)

Qt Version: 5.7.0
Frameworks Version: 5.25.0
Operating System: Linux 4.4.17-2.gdc55b9b-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

Plasmashell froze and did not respond, I killed it with 'killall plasmashell'. After restarting plasmashell from krunner, it works for a few mintes, then crashed and restarts automatically.

The crash can be reproduced sometimes.

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