Whenever a user adds my application Facebooker will throw a Facebooker::Session::IncorrectSignature exception. Upon further investigation I was finding that while the expected signature was blank, the actual signature was the facebook app secret key. why is this happening?

If I account for the signature to be blank on install, I get a SignatureTooOld exception; since facebook_sig_params['time'] is an empty value

I'm running on rails 2.1 ruby 1.86, but this has also happened on rails 2.0 and pre-2.0 versions.
Thanks in advance to anyone that can help - I'm at a complete loss.
