Passing post_status an array for a new WP_Query throws an error

[drebabels]

According to the WP_Query documentation (​http://codex.wordpress.org/Function_Reference/WP_Query#Type_.26_Status_Parameters) the post_status parameter takes either an array or string. However when you pass it an array like so

$args = array (
	'post_status' => array('inherit','publish')
);
$query = new WP_Query( $args );

The following two errors are thrown:

Warning: explode() expects parameter 2 to be string, array given in /Users/ender/Sites/soompi3k_trunk/htdocs/wp-includes/query.php on line 2369

Warning: in_array() expects parameter 2 to be array, null given in /Users/ender/Sites/soompi3k_trunk/htdocs/wp-includes/query.php on line 2378

And the SQL query looks like this:

SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts WHERE 1=1 AND wp_posts.post_type = 'post' ORDER BY wp_posts.post_date DESC LIMIT 0, 10

But pass in a comma separated string like so

$args = array (
	'post_status' => 'inherit, publish'
);
$query = new WP_Query( $args );

No errors are thrown and the resulting SQL query is what I would expect:

SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts WHERE 1=1 AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'inherit') ORDER BY wp_posts.post_date DESC LIMIT 0, 10

In any case, this is a duplicate of a ticket that already has a patch. Closing as such. See #16824
