Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 3.1.0 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I just logged in and nepomuk started crashing, everytime I restart it it crashes again.

I also noticed that virtuoso crashes also, in my dmesg I have:
[26142.998907] virtuoso-t[20125]: segfault at ffffffff ip 0846818c sp b5e70980 error 6 in virtuoso-t[8048000+985000]

Any hints?

The crash can be reproduced some of the time.

-- Backtrace:
