Application: kmail (1.99.0)
KDE Platform Version: 4.4.80 (KDE 4.4.80 (KDE 4.5 Beta1)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I added one of the KDAB test imap resources and after setting it up, KMail 2 keeps crashing on me in the defaultIdentity method. At an earlier crash it even crashed inside QList::const_iterator::operator* -> QList::Node::t - strange.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
