	Merged from stable.

	* gtk/gtktreeview.c (do_expand_collapse),
	(expand_collapse_timeout), (cancel_arrow_animation): made
	expand_collapse_timeout a wrapper with locks around
	do_expand_collapse, made cancel_arrow_animation use
	do_expand_collapse. Fixes threadlock. (Fixes #111286, patch from
	Peter Bloomfield).
