Export Bug with Taxonomies

For some time I have been struggling with exporting just those posts with a certain tag. The export never had any posts, i.e. it claimed no post satisfied the post_tag. However, I was certain that was not the case.

After much searching and attempting the patches at http://core.trac.wordpress.org/ticket/15197 (gutting filtering for now is not an option for me.), I dug a bit into the tables and I believe that wp-admin/includes/export.php has an error around Line 67 in export_wp()

if ( $taxonomy && is_array( $taxonomy ) ) {
		foreach ( $taxonomy as $term_id ) {
			if ( $term_id != 'all' )
// incorrect  				$where .= $wpdb->prepare( "AND ID IN (SELECT object_id FROM $wpdb->term_relationships WHERE term_id = %d) ", intval($term_id) );
//corrected version with tables joined on term_taxonomy key
				$where .= $wpdb->prepare( "AND ID IN (SELECT object_id FROM $wpdb->term_relationships left join $wpdb->term_taxonomy on ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id) WHERE term_id = %d) ", intval($term_id) );

I am a noob, so posting this for others to check out before submitting it as a ticket.
