Application: kmymoney (4.5.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Quite often crash with "segmentation fault message". Mostly without any specific condition. In case of using "Suggest a category" for payee it is repeatable. 
In this case it was with starting KMM with --lang=C option but the same behaviour is with standardly used language (CZ).

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMyMoney (kmymoney), signal: Segmentation fault
