Application that crashed: kontact
Version of the application: 4.3.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-gentoo-r5 x86_64

What I was doing when the application crashed:
When I tried to forward an email (account activation info from the flipside forums) Kontact crashed. 

A second try (after restart) had the same result, so I assume I can reproduce it. 

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