Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Login to KDE, start Dolphin, nepomuk crashes.
- Unusual behavior I noticed:
I get this error for about 1 year, it is really annoying.
It was OK for small time I was trying Kubuntu 11.04 betas but after finall version had been released, it started to do again!

The crash can be reproduced every time.

-- Backtrace:
