Comment 10 for bug 259169

For me, the crash (assuming it's the exact same one) happens when I have my laptop (Dell Latitude D620) in a port replicator, booted with an external monitor on the port replicator and also with the lid open.

Output of xrandr:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2432 x 864
VGA connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1360x768 59.8
   1152x864 60.0
   1024x768 60.0*
   800x600 60.3
   640x480 59.9
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
   1280x800 60.0 +
   1024x768 85.0 75.0 70.1 60.0*
   832x624 74.6
   800x600 85.1 72.2 75.0 60.3 56.2
   640x480 85.0 72.8 75.0 59.9
   720x400 85.0
   640x400 85.1
   640x350 85.1

The laptop built-in display is blank at this point. Running gnome-display-properties will crash. If I run xrandr --output LVDS --mode 1280x800, the built-in display comes up (with the semi-expected panel sizing problems), and running 'gnome-display-properties' will work properly.
