Bug 280065

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Strigi index my homedir and kmail remove a lot of duplicate mails. So i can't say what the problem.

- Unusual behavior I noticed:
High CPU usage. Sometimes no interaction with mouse possible.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Nepomuk-Dienst (nepomukservicestub), signal: Aborted
