Application: kontact (4.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686

-- Information about the crash:
This happens to me frequently, but not always. 

Steps to reproduce:

1. Start Kontact, switch to mail, which includes an IMAP account
2. Lose connection to IMAP account (happens to me usually due to poor wifi)
3. Quit Kontact
4. Restart Kontact
=> crash

Everything works fine upon second restart.

The crash can be reproduced some of the time.
