[Plugin: WP-FacebookConnect] Facebook Connect breaks comments feed.

I’ve been using the WP-FacebookConnect plugin for a couple of weeks now and have been very happy, but I’ve just clicked on my comments feed and found that it’s broken with an error on this line –

<fb:name linked=”false” useyou=”false” uid=”741802438″>Charles Thompson</fb:name>

I tried routing it through feedburner since I know that it can sometimes fix errors, but too pointed to the problem

“The prefix “fb” for element “fb:name” is not bound”
