After special pages got moved to includes/special/ this patch was not brought over: http://www.mediawiki.org/wiki/Special:Code/MediaWiki/25944. Don't know much more for now.
I guess this is not relevant nowadays, but the missing patch mentions "security" so I'd rather copy Chris & Sam to weigh in. If this is not relevant then please resolve WORKSFORME or WONTFIX. Thank you!
Volodymyr: Do you know if this is still a problem in a recent version of MediaWiki (1.19 or prefably newer)?
Code is definitely in current codebase: https://git.wikimedia.org/blob/mediawiki%2Fcore.git/HEAD/includes%2FFeedUtils.php#L107 Closing as obsolete.
