Bug 322439

Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.9-201.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

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

First login after a fresh boot. This used to happen frequently, but seemed to go away for the last few months. Now it has re-appeared. When it happens it is always after a cold start (reboot) on initial login.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
