Bug 315823

Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic i686
Distribution: Ubuntu 12.10

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

Since KDE instalation the nepomuk file indexing service was enabled. Than I realized, that my new ssd disk should be fast enough to handle the indexing load, so I enabled the service in nepomuk configuration dialog.

Than I've opened the nepomuk controller dialog and let the process run - it seemed to have loads of work to do. After a while without any input the screen locked itself. Than I unlocked the session and  KDE crash handler poped up allowing to generate this traceback.

This occured multiple times, everytime I tried to let file indexing service to run continuously for a longer time with a lot of files to be indexed.


- Custom settings of the application:

Nepomuk file indexing service disabled since installation, than re-enabled again.

The crash can be reproduced every time.
