	* panel-util.c: (panel_lock_screen_action_available),
	(panel_lock_screen_action): check the lock screen lockdown setting
	before doing anything. The UI is already blocking the user for locking
	the screen (by making the widget non-sensitive, eg), but this is extra
	safety.
	* gnome-desktop-item-edit.c: update to make it compile because of this
	change...
	Based on a patch from Matt Keenan <matt.keenan@sun.com>
	Part of bug #522453
