Comment (by sc0ttkclark):

 delete_metadata uses this:


 {{{
 if ( $meta_value )
     $query .= $wpdb->prepare(" AND meta_value = %s", $meta_value );
 }}}

 It should probably be:

 {{{
 if ( '' !== $meta_value && null !== $meta_value )
     $query .= $wpdb->prepare(" AND meta_value = %s", $meta_value );
 }}}
