Bug 299355

Application: kmail (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.3.3-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
I selected the INBOX of one of my IMAP accounts, then kmail crashed. Since then I cannot use kmail anymore because it crashes right after startup this the attached BT.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
