OAuth::RequestProxy::UnknownRequestType with Rails 3

[Justin]

I've been using the OAuth gem with Rails 3 and I kept running into
this error especially when testing with rspec:
OAuth::RequestProxy::UnknownRequestType

In case anyone else has the same problem there's an issue submitted
that includes code by KentonWhite that fixes the problem:
https://github.com/oauth/oauth-ruby/issues/13

What would it take to get this code into the core so that Rails 3 is
fully supported?

Thanks,
Justin
