Problem with tax_query

I am running a simple tax query with multiple arrays (taxonomies). I am noticing that the code is adding to the where clause with a table alias ‘tt1’ but not adding the table in the inner join. I have come to the following lines:

if ($clauses['join'] && $taxonomies[ 'join' ] && strpos( $clauses[ 'join' ], $taxonomies[ 'join' ] ) === false )
    $clauses[ 'join' ] .= $taxonomies[ 'join' ];

and changed it to:

if ($taxonomies[ 'join' ] && strpos( $clauses[ 'join' ], $taxonomies[ 'join' ] ) === false )
    $clauses[ 'join' ] .= $taxonomies[ 'join' ];

I do not believe this will work for everything, but it has worked for me now. I wanted to alert you of the problem and maybe push out a proper fix. When I have time to actually look into what can possibly be making it wrong and then make it right I will (if not previously fixed)
