	* gtk/gtkliststore.c (gtk_list_store_move): added checks to ensure
	that the iter is not reordered to its own position. Prevents model
	corruption for the case that the store contains only a single item
	(fixes bug #108387).

	Unrelated:

	* gtk/gtkliststore.c (gtk_list_store_insert): g_list_alloc() the
	new list element later so we don't leak it if we decide to return
	early.

	* gtk/gtktreeselection.c (_gtk_tree_selection_internal_select_node):
	set selection->tree_view->priv->anchor to NULL after freeing it.
