The system is a Dell Laitude D630n with nVidia NVS135M.

>Description:
	When physical display changes, e.g. connecting to an external monitor
before boot, or disconect it, the first 'startx' will crash:

pid 1861 (gnome-settings-daem), uid 1001: exited on signal 6

>How-To-Repeat:
>Fix:

	It seems starting gnome-control-center, in "Monitors" click
"Apply", then gnome-settings-daemon can be started properly.

	My gut call is that there is some invalid assert in
gnome-settings-daemon but I haven't investigated that much.
