	Fixes from David Hampton <hampton@employees.org> via gtk-devel-list.

	* gtk/gtktreemodelfilter.c (gtk_tree_model_filter_elt_get_path): fix
	the call to gtk_tree_model_filter_add_root,
	(gtk_tree_model_filter_row_changed): bail out if c_path is not above
	the virtual root, allow building levels on the second try to convert
	the child path to a filter path,
	(gtk_tree_model_filter_convert_iter_to_child_iter): pass the virtual
	root when calling gtk_tree_model_filter_elt_get_path.
