Description Hans 2017-07-01 13:45:21 UTC 
Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.73-18.17-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
The crash came while I was closing the programs Firefox, Libre office writer and PDF Okular.  Therefore the desktop was locked and i pluged in a external monitor unlocked and after that KDE was acting slowly. To fix this slow acting a was clossing the programs for a restart

The crash can be reproduced sometimes.

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