Evidently, self.body can't be None but is always being set to None for GET requests.

Here is the problem line in oauth2/init.py...

if not self.is_form_encoded:
488 # according to
489 # http://oauth.googlecode.com/svn/spec/ext/body_hash/1.0/oauth-bodyhash.html
490 # section 4.1.1 "OAuth Consumers MUST NOT include an
491 # oauth_body_hash parameter on requests with form-encoded
492 # request bodies."
493 self['oauth_body_hash'] = base64.b64encode(sha(self.body).digest())
