I was working on diagnosing bug 868354 (Duplicate indicators bar and desktops with overlapped screens) by running the gnome-display-properties applet on a laptop with external monitor. I was enabling/disabling the displays and moving them around to different orientations.
At one point I (roughly) centered the smaller laptop display above the external monitor, hit apply, and the system locked up. dmesg shows:
