Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

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

I surfed on the web a bit, then i closed chromium and i pushed the shutdown button, but a bug segnalation appeared to me.
In this moment I'm writing on that segnalation with no desktop (only black screen + bug window).

-- Backtrace:
