Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-27-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
I suspect it might be related to having a multiple screen setup, because there are continuous messages of kscreen

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
