Bug 275504

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 i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Nepomuk has crashed twice in the past two days. The first time, I was watching a video on VLC, and the second time, I was talking on Skype. The first time, every time I tried to restart Nepomuk, it would crash again.

- Custom settings of the application:
Last time kpackagekit was updating this computer to KDESC 4.6.4, it stalled. I restarted the computer before all of the packages finished installing. Afterwards, I couldn't see my updates again, so I haven't bothered trying to get them back. I don't know if this could be affecting my situation or not.

The crash can be reproduced some of the time.

-- Backtrace:
