Application: kontact (4.4.10)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: When it happens I mostly work with another program, this time with libreoffice. 

- Unusual behavior I noticed: It seems Kmail is looking for new emails and the response of the provider-server may last to long.

- Custom settings of the application: There are several mailboxes, IMAP and POP, but no special settings. Maybe there is a settings-file I could send, but I don't know where.

The crash can be reproduced every time.

-- Backtrace:
