In my case, I tryin to set wpquery's "author_name" array value to "" on Author page, so it'd returning all posts from every users. (because for several reason and development awesomeness, i need this)

function test_pre_get_posts($query) {

  if ($query->is_author && $query->is_main_query()) {
    $query->set('author_name', '');

  return $query;

horray, now it's returning the stuffs all i wanted.
but hol'up! now this ugly creature appears: "Notice: Trying to get property of non-object in C:\xampp\htdocs\wp-includes\class-wp-query.php on line ..."

let's put aside the line of the codes, here is where the problem happened. on public function is_author( ... ):

$author_obj = $this->get_queried_object();

$author = array_map( 'strval', (array) $author );

if ( in_array( (string) $author_obj->ID, $author ) )
  return true;
elseif ( in_array( $author_obj->nickname, $author ) )
  return true;
elseif ( in_array( $author_obj->user_nicename, $author ) )
  return true;

return false;

cool stuff, but could you guys give another validation for this thing like uhh

if (empty($author_obj->ID))
  return false;

or something above those conditional stuff that returns true? so it wouldn't produce error notice as I mentioned before.
