22746	The metadata_exists() function should return the correct value if the get_$meta_type_metadata filter returns a non null value	xknown		"The line [http://core.trac.wordpress.org/browser/trunk/wp-includes/meta.php?rev=23043#L324 324] should return $check instead of true, otherwise the filter doesn't normally work when someone wants to always return false for a given meta key.

Here's a quick way to reproduce it
{{{
> add_filter('get_user_metadata', '__return_false'); return metadata_exists('user', 1, 1)
TRUE
}}}"	defect (bug)	new	normal	Awaiting Review	General		normal
