Bug 346555

Application: plasmashell (5.2.95)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed: Booted after Upgrade 14.10 -> 15.04

Notes: 
- Krunner also crashes
- Using lightdm (sddm does not show anything at all)

The crash can be reproduced every time.

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