Bug 322992

Application: kmail (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.9.10-200.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
Kmail was running when internet connection failed. After that it crashed.
And it crashes every time I start it. Haven't  tried logging out and in again yet.

The crash can be reproduced every time.

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