Bug 312524

Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.9.95
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
I had just upgraded to 4.10beta2 and restarted my desktop (via c-a-backspace).  I left the system idle overnight.  In the morning nepomuk had SIGABRTed spontaneously.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
