Bug 350873

Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.3-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
I did a routine FC22 system update on 08/01, system would reboot fine, KDE would start just fine.
This AM, however, it started crashing right after every login (via kdm).

The crash can be reproduced every time.

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