Description Florian Evers 2010-11-05 22:32:36 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.5.3 (KDE 4.5.3) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.36-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

This crash happens each time I shut down KDE. This is totally independent of what I did or how long I was logged in. After selecting "log off", there is a lag of several seconds before KDE starts to shut down visibly and nepomukservicestub crashes. Perhaps that lag is related to this crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Nepomuk-Dienst (nepomukservicestub), signal: Segmentation fault
The current source language is "auto; currently asm".
