Sentry Crash Report:

Description drdrnewman 2013-06-07 11:20:16 UTC 
Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.3
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:

I left the computer for an hour, with the monitor switched off. At some time nepomukserverstub crashed, after two things had happened: KDE tried to dim the screen, and avidemux started converting a video file (not saved in a directory indexed by nepomuk, but it can create temporary files elsewhere). I don't know if either of those events is connected to the crash.

The crash can be reproduced every time.

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