	* gtk/gtktreeview.c (gtk_tree_view_check_dirty): handle case where
	there are no rows in the model

	* gtk/gtkliststore.c (gtk_list_store_iter_children): if parent is
	NULL, then return the start of the list

	* gtk/gtktreeview.c (gtk_tree_view_setup_model): don't build tree
	if we can't get any rows from an empty model

	* gtk/gtktreeviewcolumn.h (struct _GtkTreeViewColumn): remove
	extraneous * after function pointer typedef usage

	* Makefile.am: don't specify full path to cp and rm

	* gtk/gtkcellrenderertextpixbuf.c
	(gtk_cell_renderer_text_pixbuf_get_size): check width/height !=
	NULL before dereferencing, fixes a segfault that happened from
	time to time

	* gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_render):
	use gdk_pixbuf_render_to_drawable_alpha() to get alpha channel,
	and reindent the function
	(gtk_cell_renderer_pixbuf_get_size): indentation

	* gtk/gtkdialog.c (gtk_dialog_run): destroy main loop only after
	we quit it
	(gtk_dialog_add_buttons_valist): add g_return_if_fail
	(gtk_dialog_set_default_response): New function, to set default
	button
	(gtk_dialog_set_response_sensitive): New function, to set
	sensitivity of buttons

	* gtk/gtkcellrendererpixbuf.c
	(gtk_cell_renderer_pixbuf_get_property): allow getting a NULL pixbuf
	(gtk_cell_renderer_pixbuf_set_property): allow setting a NULL pixbuf

	* gtk/gtktreedatalist.c (_gtk_tree_data_list_node_to_value):
	handle any G_TYPE_OBJECT subclass, not just the base class, and
	also boxed types.
	(_gtk_tree_data_list_value_to_node): ditto

	* gtk/gtkrbtree.c: Run _gtk_rbtree_test at strategic points if
	--gtk-debug=tree

	* gtk/gtkmain.c: add GTK_DEBUG_TREE

	* gtk/gtkdebug.h: add GTK_DEBUG_TREE
