Got a PHP warning: class-wp-xmlrpc-server.php L596: array_unshift() ...

Sometimes the php_error.log file got a warning:

PHP Warning:  array_unshift() expects parameter 1 to be array, null given in /wp-includes/class-wp-xmlrpc-server.php on line 596

<?php
public function wp_getUsersBlogs( $args ) {
        // If this isn't on WPMU then just use blogger_getUsersBlogs
        if ( !is_multisite() ) {
                array_unshift( $args, 1 );
                return $this->blogger_getUsersBlogs( $args );
        }
...
}

The $args is NULL, it doesn't matter?

Possible duplicate of #29750?

I'm getting this too, 5 months after #29750 was marked as "fixed".
