Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was removing categories dubblets within contacts (after I've imported vCards from Evolution). After deleting some cateories the program crased. This has happend at least twice.

I feel that Kontact is slower compared to Evolution, both when admin in contacts and calender. 

Good hunting!
/Magnus

The crash can be reproduced every time.
