is swapped out).

	* src/file-manager/fm-directory-view.c: (fm_directory_view_destroy):
	While debugging, I noticed that the view_frame was allocated by the
	FMDirectoryView and never unref'd. The exact connection of this to
	why the widgets don't go away is now lost in time. We added a call
	to bonobo_object_unref to get rid of the view frame.

	* src/ntl-window.h, src/ntl-window.c, src/ntl-window-msgs.c:
	(Nautilus_NavigationInfo_free): Got rid of this routine. It turns
	out that this was an incorrect hack to work around the error in
	the surrounding code that was copying CORBA object references
	without calling	CORBA_Object_duplicate.
	(nautilus_window_destroy), (nautilus_window_request_selection_change):
	Changed code that was calling Nautilus_NavigationInfo_free to just
	call CORBA_free now that the incorrect hack is not needed.
	(nautilus_window_request_selection_change),
	(nautilus_window_update_view),
	(nautilus_window_update_internals),
	(nautilus_window_load_content_view): Changed all code that was
	manipulating content_view to use CORBA_Object_duplicate when
	storing a reference and CORBA_Object_release when overwriting
	a reference.
