Bug 275553

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- Unusual behavior I noticed:
The Nepomuk crashes randomily, sometimes when I open dolphin, this time when I closed some windows. Please do something with it, it is really annoying.
Thanks
T.Kijas

The crash can be reproduced every time.

-- Backtrace:
Application: Pahýl služby Nepomuk (nepomukservicestub), signal: Segmentation fault
