Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0) "release 152"
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:
Selected a largeish png (2000 x 1024) in dolphin from usb stick and double-clicked it (one click opens the viewer). Two instances pop up and one of them crashes. Can't repeat it though.
