Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

I was waiting for a very full waste bin to empty.

The only other thing I was doing at the time was clicking around a bit of Flash in Firefox, so unlikly to be relevent.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
