gnome-control-center crashed with SIGSEGV in gnome_rr_config_new_current ()

[Avi Greenbury]

I opened the control center to adjust the monitors settings. I double clicked on the monitors icon and nothing appeared to happen. I double clicked again and the control center disappeared, and then the control center disappeared. I was then asked if I'd like to submit a bug report, so I did :)

About a minute previously the panel crashed and offered me the chance to submit a report, but I clicked the wrong button and didn't.

I don't appear to be able to reproduce this right now.
