Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.1 (KDE 4.3.1) "release 169"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.29-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
I received a message with a html part. I finally clicked to allow also picture from the Internet to be shown. After that Kontact/KMail was in a loop using all CPU. After that I had to leave the computer and left things running. After 6 hours Kontact still was using all CPU. Using Ctrl+Alt+Esc and clicking on the Kontact window I got this crash of Kontact.
Will see if this is reproducable.

 -- Backtrace:
