Bug 280516

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-8-generic x86_64
Distribution: Ubuntu oneiric (development branch)

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

I'm enabled nepomuk today, after ~5 hours running (all files was indexed before, so it was idle) this crash report is appeared. Sorry if it's dup, but I'm not found same report (with QRegExp fail).

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
