I'm running a MediaWiki 1.4.6 and I've noticed that the RSS (and atom) feed from Special:Recentchanges has become invalid.
As far as I can tell two blank lines are being inserted before the header and these seems to break any attempt to parse it using a newsreader.
I've looked at the code and I can't see anything wrong with the headers. I haven't modified the code at all.
The feed is @ http://irishgamingwiki.com/index.php?title=Special:Recentchanges&feed=rs...
and here is what a validator says about it:

Thanks for any help Mark Cunningham
