Description Stewart Peters 2013-01-10 19:04:38 UTC 
Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.9.97
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
It would appear that whilst scanning through media on my system on every boot it requires to overwrite previously obtained images, produces errors that it is unable to write to certain locations, then crashes.  This happens on every boot, though on some boots it also prompts to match a TV series from a list generated from tvdb, though it never indicates what file or folder it is currently looking at, making it hard in some instances to know what is the correct choice.

The crash can be reproduced every time.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi

nepomukservicestub (0.1.0) on KDE Platform 4.10.1 using Qt 4.8.4

- What I was doing when the application crashed:

I just started KDE and plugged the charging cable into my laptop. Sortly after this, Nepomuk crashed.
