Description Andrea 2011-12-01 10:05:49 UTC
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I had just logged in; previously I had deactivated Nepomuk altogether but thanks to the constant nag messages that can't be deactivated (this is a wishlist item already apparently) I activated nepomuk and now I get crashes.

- Custom settings of the application:
In system settings (all settings): 
- Enabled Nepomuk Semantic Desktop (previously disabled! -> led to nag messages, so enabled)
- Strigi disabled
- no automatic backups
- 50 MB upper limit for nepomuk's database process

Platform: 
Ubuntu 11.10 (oneiric)
Linux some-desktop 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
KDE 4.7.2

The crash can be reproduced every time.

New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:

The same as above: I just log in.

Also plasma-desktop uses 100% cpu on startup for about 2 Minutes. After that anything is normal.
Don'tknow if it's related though.
