-- 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
