	* gtk/gtktreeview.c (gtk_tree_view_real_select_cursor_row): For
	some reason, I was activating a row while just selecting it.
	Reported by andersca.
	(gtk_tree_view_size_request): add a
	validate_rows_handler to give us a rough width of the widget.

	* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_update_button):
	Queue a resize here just in case.  It's needed in over half the
	cases, and I don't want to do a diff to figure out exactly when
	it's needed.
