	* em-folder-tree.c (em_folder_tree_get_folder_info__got): Make
	sure our parent folder hasn't been unsubscribed or else we get a
	segfault here if it has.

03-11-28  Dave Camp  <dave@ximian.com>

	* em-folder-tree.c (render_pixbuf): Set the pixbuf renderer
	invisible for stores.

2003-11-25  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-config.c (mail_config_get_account_by_uid): New function.

	* em-folder-tree.c (tree_store_set_folder_info): Expand the tree
	node if the saved state tells us it was expanded the previous
	session.
	(em_folder_tree_load_state): Load the saved state.
	(em_folder_tree_add_store): Conditionally expand the store node.
	(em_folder_tree_new_with_model): Expand all the nodes that should
	be expanded.
