Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-32-generic x86_64
Distribution: Ubuntu 13.04

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

Pressed Ctrl-Q while kmailpart was active.

Again, it crashed, while following a slightly different code path than bug 288141 (the reason I'm filing a separate report).

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
