Bug 280633

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- Kontact was open. Kmail was still updating my IMAP account and syncronizing after startup. (It is very slow, maybe because the use of mbox format instead of maildir).
I was browsing internet using Firefox.

-- Backtrace:
Application: Matriz de servicio Nepomuk (nepomukservicestub), signal: Aborted
