Application that crashed: kwin Version of the application: 4.3.00 (KDE 4.3.0) KDE Version: 4.3.00 (KDE 4.3.0) Qt Version: 4.5.2 Operating System: Linux 2.6.30-1-amd64 x86_64 Distribution: Debian GNU/Linux 5.0.2 (lenny) What I was doing when the application crashed: I moved from Mozilla (read Icedove) to the terminal (read console), or wanted to at least. Normally I do this with ALT-TAB, but I cannot tell 100%ish since I don't notice doing it :) Firefox (Iceweasel) was also open. Not much else, really. No sound was playing. No special periphery, except a USB trackball and a USB keyboard, but I experience the same bug also when using tha laptop's keyboard with nothing attached. No second monitor.
