Bug 257307

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.6.3
Operating System: Linux 2.6.36-zgws1 i686
Distribution: Debian GNU/Linux unstable (sid)

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

When I work with KDE, Nepomuk indexes my disk. This takes hours per day with the CPU churning away at highest load with highest temperature (I have never seen my notebook run _this_ hot before).

After some hours, nepomuk crashes with the attached backtrace.

I'm going to disable nepomuk/strigi/indexing/whatever for the time being.

Greetings
Marc

The crash can be reproduced some of the time.
