Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-gentoo-r2 x86_64

What I was doing when the application crashed:
I was simply typing an e-mail in KMail when plasma crashed.  I'm using NVidia drivers with compositing, but wasn't doing anything that seems related to the crash.
