23005	wp_update_user breaks if ID not set	actionnerd		"Passing an array of userdata to wp_update_user (first_name, last_name, user_email, user_login).

If ID is not in the array, then a PHP Fatal Error is triggered: 
[19-Dec-2012 15:03:16 UTC] PHP Fatal error:  Call to a member function to_array() on a non-object in [..]/web/content/wp-includes/user.php on line 1456

The codex for wp_update_user (http://codex.wordpress.org/Function_Reference/wp_update_user) does state ""If $userdata does not contain an 'ID' key, then a new user will be created and the new user's ID will be returned."", which makes me think this might be a new bug."	defect (bug)	new	normal	Awaiting Review	Users	3.5	normal
