Bug 293254

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-13-generic x86_64
Distribution: Ubuntu 11.04

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

Rendering an H.264 video in an MP4 container. Nepomuk always crashes when doing this, and only when doing this. Kubuntu 11.04, everything installed from official Ubuntu repos.

The crash can be reproduced every time.

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