Application that crashed: kmail
Version of the application: 1.12.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.8-64.fc11.x86_64 x86_64

What I was doing when the application crashed:
The text view of my email looked fine. I clicked the inline html view from message contents pane. It displayed, then after a second or two it refreshed. Then it refreshed again a couple of times, then kmail crashed.

The email had a pdf attachment.
