Bug 350666

Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.0.8-300.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Krunner crashes after every startup, starting with the .7 update.  Restarting sddm does not fix the problem.

Setting autologin to on allows me to access programs which were open on the desktop before restart, otherwise the login page does not load.  No desktop or application launcher available.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
