Comment (by coolmann):

 Alternatively, instead of changing line 1078 as suggested above, line 1050
 in template.php could be changed from

 `if ( ! isset( $wp_meta_boxes[ $page ][ $a_context ][ $a_priority ][ $id ]
 ) ) {`

 to

 `if ( empty( $wp_meta_boxes[ $page ][ $a_context ][ $a_priority ][ $id ] )
 ) {`
