 I've altered the default orderby of pages list table like so:

 {{{
 function my_pre_get_posts($query)
 {
         if(!$query->is_main_query() && $query->query['post_type'] !=
 'page')
                 return;

         $query->set('orderby', array('menu_order' => 'asc', 'title' =>
 'desc'));
 }


 add_action('pre_get_posts', 'my_pre_get_posts');
 }}}

 and I get a PHP Notice caused by strtolower() in get_orderby() method
 which tries to lower an array in my case.

 It worked fine up to 4.3.x.
