	[ patch contributed by Jos Dehaes <jos.dehaes@bigfoot.com> ]

	* gui/component/addressbook-storage.c (register_storage): new
	function, register our evolution_storage.
	(addressbook_storage_setup): remove storage registration from
	here.
	(load_source_data): register the storage here before we load
	addressbook-sources.xml, and deregister it if there are no sources
	listed.
	(addressbook_storage_remove_source): unregister the storage if the
	list of sources hits 0 length.
