2001-07-30  Jason Leach  <jleach@ximian.com>

	* gui/component/addressbook-storage.c (load_source_data): Fix a
	return value bug, to make it so if it fails to load an
	addressbook-sources.xml file (either a parse error or it doesn't
	exist for example), it deregisters the storage.
	(register_storage): Don't make a storage for users who don't have
	LDAP support built in.  Bug #1950.
