Bug 349217

Application: plasmashell (5.3.1)

Qt Version: 5.4.2
Operating System: Linux 4.0.4-303.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
Updated Fedora 22 which included plasma 5.3.1. Then Plasma srash every time login. So KDE is now un-usable

The crash can be reproduced every time.

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