Application: kontact (4.4.9)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-26-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Kontact has just started to Summary screen, new mail notification was displayed, so I have clicked on link to the Inbox folder.

Additional information - overall Kontact stability has deteriorated since I have added IMAP account, however in this case IMAP wasn't monitored on the summary screen and the Inbox folder contains only mail from POP3 accounts.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
