[Plugin: WP Facebook Open Graph protocol] Facebook debug error with fb:page_id

Hi,
I’m getting the following error when debugging for http://textfails.com/:
Extraneous Property: Objects of this type do not allow properties named ‘fb:page_id’.

Parser Mismatched Metadata:
The parser’s result for this metadata did not match the input metadata. Likely, this was caused by the data being ordered in an unexpected way, multiple values being given for a property only expecting a single value, or property values for a given property being mismatched. Here are the input property =>content pairs that were not seen in the parsed result: ‘og:locale:locale => en_US, og:title => No, he’s not hurt…, fb:page_id => 110127269036518, og:locale:locale => en_US’
