Bug 317071

Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.0-13-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Starting KDE. I had rebooted after building nepomuk core and akonadi/kdepim  from master.

I had two nepomukservicestub processes and one was using 100% of one core and was at 500MB+ of RAM and rapidly increasing. I killed it and got this crash report.

The crash can be reproduced sometimes.

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