Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-22-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed and unusual behavior I noticed:
Before I created new sessions and switch to it and switched back -> kwin crashes
After a reboot -> sddm showed login animation -> resettet
after deleting .local folder -> sddm could log me in -> this crash occured after some time

The crash can be reproduced every time.

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