Bug 303121

Application: kmail (1.13.7)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.2
Operating System: FreeBSD 9.0-RELEASE-p3 i386
Distribution (Platform): FreeBSD Ports

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

My KMail account was set up to connect to Gmail's IMAPS service. I right clicked the Spam folder to "Mark All Messages as Read." This usually works, but crashed this once.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault: 11
