	Fixed bug 6689, Segmentation fault from volume_in_black_list after
	the death of the desktop.

	* src/file-manager/fm-desktop-icon-view.c: (volume_in_black_list):
	Add an assert to catch a NULL icon view being passed in.  We need to
	find out why this happens if it ever does.

	* src/nautilus-application.c: (window_can_be_closed),
	(is_last_closable_window), (volume_unmounted_callback):
	Handle single window case in the code where we close the windows
	the are displaying the contents of the unmounted volume.  In the case
	of a single window, direct it back to the default home directory.
