Bug 240554

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.4.82 (KDE 4.4.82 (KDE 4.5 >= 20100601)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was just running my usual desktop applications. The crash occurs during some changes to Plasma configurations, doesn't seem to happen everytime. Also crashes when plasma-desktop quits manually using kquitapp.

The crash can be reproduced some of the time.

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