Application: plasmashell (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed: The Nvidia driver does not store all monitor settings after logout. After every reboot, the left and the right screen are exchanged. I fix this by switching physically the two monitore. However, sometimes Plasma crashes during this procedure.

The crash can be reproduced sometimes.

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