Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-23-generic x86_64
Distribution: Ubuntu 13.04

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

Nothing. I had relogged in to KDE after kded had crashed.

However, a script had started to save an MP4 file, that would not be ready for indexing for a while.

- Unusual behavior I noticed:

The warning of the crashed nepumukserverstub came up when I looked at the screen after 30 min.

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