Bug 294400

Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.2-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Restarted the WiFi system, which had gone offline, and reconnected to it.  Clicked Get Mail, read the two resulting messages.  Hit Ctrl-Q to exit Kmail.  The crash reporting assistant popped up, and here we are.  I noticed no strange behavior other than the crash.

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