Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I was ripping an audio CD with k3b, while several applications (chromium, iceweasel and icedove) were open in the background. No Flash running. Midway through ripping, nepomuk crashed. There was no loss of data, ripping finished regularly. Only the usual "I (nepomuk) just crashed". It happened earlier this week, another user account, while downloading a file from the net.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault
