Comment (by dd32):

 This while loop is also in `wp_widget_rss_output()`.

 At the most basic just prefixing a boolean `$url` check would probably do
 - [attachment:"53278.diff"].

 Looks like SimplePie might also be affected by the change in PHP behaviour
 due to it's strict type check
 {{{
 ./SimplePie/IRI.php:916: if (($port = substr($remaining, $port_start + 1))
 === false)
 }}}
