Comment (by archon810):

 While we're waiting for this fix, I'm also seeing a similar issue in `wp-
 includes/class-wp-http-ixr-client.php`.

 {{{
 ErrorException: Undefined index: host
 #7 wp-includes/class-wp-http-ixr-client.php(27): handleError
 #6 wp-includes/class-wp-http-ixr-client.php(27): __construct
 #5 wp-includes/comment.php(2652): pingback
 #4 wp-includes/comment.php(2486): do_all_pings
 #3 wp-includes/class-wp-hook.php(286): apply_filters
 #2 wp-includes/class-wp-hook.php(310): do_action
 #1 wp-includes/plugin.php(515): do_action_ref_array
 #0 wp-cron.php(126): null
 }}}

 Same for
 {{{
 Undefined index: scheme
 }}}

 Examining the `$bits` variable, I see this:

 {{{
 bits
 {
     path: /wordpress/xmlrpc.php
 }
 }}}

 The function this happens in:

 {{{#!php
 <?php
 public function __construct($server, $path = false, $port = false,
 $timeout = 15) {
                 if ( ! $path ) {
                         // Assume we have been given a URL instead
                         $bits = parse_url($server);
                         $this->scheme = $bits['scheme'];
                         $this->server = $bits['host'];
                         $this->port = isset($bits['port']) ? $bits['port']
 : $port;
                         $this->path = !empty($bits['path']) ?
 $bits['path'] : '/';
 }}}

 All such errors are caused by `wordpress/wp-cron.php?doing_wp_cron`.

 Perhaps the fix here can also be applied to `class-wp-http-ixr-
 client.php`?

 Thank you.
