Application: kmail (1.13.6)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
I've added a second IMAP account and since the next start of Kmail it crashed after entering the passwords for the two accounts. The first account is on a Scalix server and is in use since several years and the second account is from a Zarafa server using a SSH tunnel and was added recently. After adding this account there weren't any problem, these occured on the first new start of Kmail. When I close the SSH session and there's a connection refused on this port Kmail still crashes.
I've upgraded from 4:4.4.7-3 from Debian Squeeze to 4:4.4.10-0r3 from "deb http://qt-kde.debian.net/debian experimental-snapshots main", but this error still occurs.

Thanks
Dominic

The crash can be reproduced every time.
