Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Nothing special... Everyday PC usage and this crash is a very usual since I upgraded to KDE 4.7.0.
Mostly when I mess with my photos!

The crash can be reproduced some of the time.

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