	Fix #410815, reported by Lucas Rocha.

	* gtk/gtkiconview.c (gtk_icon_view_layout): determine a suitable
	wrap-width with the first icon, if it exists,
	(adjust_wrap_width): try to use icon_view->priv->item_width
	if available,
	(gtk_icon_view_set_cell_data): don't call adjust_wrap_width here,
	which caused changes in wrap-width during the layouting process and
	resulted in layouting artefacts,
	(update_text_cell): don't set the wrap-width property, this should
	be handled by adjust_wrap_width.
