Bug 249997

Application: kmail (2.0 beta1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.6-47.fc13.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Kmail 2 crashed on close with attached backtrace. prior to me closing it two strange things were happening: 1) more than one menu item remained greyed out as if selected (Tools, Settings and Go) and 2) a fragment of text remained in the filter box that I could not select or delete but which was not filtering the messages.

The crash can be reproduced some of the time.

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