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:
I tried to send a mail, but sending failed (needed to receive first). 

Then I found an error in the mail (view in outbox, not yet edit window). 

I doubleclicked it and Kontact died. 

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