Application: kded4 (4.13.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Logging into KDE desktop

- Unusual behavior I noticed:
KDE crashes immediately on login

openSUSE 13.1 for x86_64
Linux 3.11.10-7-desktop x86_64
KDE 4.13.0 installed from official openSUSE repositories

The crash can be reproduced every time.

-- Backtrace:
