Application: kmail (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.8-hardened x86_64
Distribution (Platform): Gentoo Packages

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

Right-clicked on a folder, intending to "mark all as read". Realized I chose the wrong folder (on with no unread mail) and quickly retried with the corrected folder. Kmail crashed after displaying the folder context menu for a split-second.

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