Bug 341371

Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.6-2-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: started kde with firefox

- Unusual behavior I noticed: kde was very slowly and a d-bus connection error for thunderbird was shown.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".
