Application that crashed: kmail
Version of the application: 1.11.90
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-gentoo-r3 x86_64

What I was doing when the application crashed:
I was forwarding (as an attachment) a message containing two big photos (~ 3 MB each). I wrote only a few words into the accompanying mail. It took several seconds to send, and as the progress bar hit 100% (or at least it seemed to me so), kmail crashed.

 -- Backtrace:
