	* gtk/gtkfilechooserdefault.c (remove_settings_signal): New
	function, copied from gtkpathbar.c.
	(gtk_file_chooser_default_dispose): Use remove_settings_signal()
	rather than our own code.
	(gtk_file_chooser_default_screen_changed): Use
	remove_settings_signal(); this should handle per-screen settings
	correctly.
