Application: systemsettings (1.0)
KDE Platform Version: 4.9.95
Qt Version: 4.8.4
Operating System: Linux 3.6.11-3.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I've closed it.

- Unusual behavior I noticed:
virtuoso-t was using my cpu for a very long time, but only less than 20 files where indexed. I've set the memory available from 50 mb to 1 gb, then I've restarted the service (apply / stop -> apply / start -> apply) and I've noticed an akonadi_nepomuk process consuming all my cpu. Then I've closed the settings panel and it crashed.

-- Backtrace:
Application: Impostazioni di sistema (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
