2001-08-13  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-store.c (camel_store_get_folder): We need to be ref'ing
	the folder if/when we add it to the hash. This may fix bug #6089?
	(camel_store_get_folder): Nevermind, reverted the fix.
	(camel_store_get_folder): No, I wasn't on crack before after
	all...if we don't ref here, then we're open to a race condition
	later.
