Application: kontact (4.6 beta4)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

Today after I logged in as usual I opened Kontact, but to my surprise it it didn't show any content in the message list, it had a blank message list and also if I remember correctly a blank list of the directory structure of the IMAP account. I waited for ten seconds or so for everything to show up, but nothing happened. I decided to close Kontact with the intention to start it again, but it crashed. This has never happened before to me in the two months I’ve been using the Kontact 4.6 beta's, normally it would open fine and my message list and everything would be visible in two or three seconds.

-- Backtrace:
