Empty delimiter in .../wp-includes/class-wp-xmlrpc-server.php on line 2469 Warning:  Cannot modify header information - headers already sent by (output started at .../wp-includes/class-wp-xmlrpc-server.php:2469) in .../webraces/wp-includes/class-IXR.php on line 471

The line 2469 of class-wp-xmlrpc-server.php looks like:

if ( strpos( $post_content, $file->guid ) !== false )

Apparently $file->guid has invalid value as this is fixed by inserting

if($file->guid && !($file->guid == NULL))
