2000-07-22  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (get_folder): Clear CamelExceptions when
	appropriate (eg when folder is marked as \NoSelect). Still needs some
	cleanup and perhaps Dan will have a better way of doing this as this seems
	like a messy way of handling this.

	* providers/imap/camel-imap-folder.c (imap_get_uids): Took out some debug
	statements as they are no longer needed.
