GAE - Deployment Error: “AttributeError: can't set attribute”

When I try to deploy my app I get the following error:

Starting update of app: flyingbat123, version: 0-1
Getting current resource limits.

The error message indicates that there is a bug in our SDK. Because of this bug, you can not see the reason of the failure. However, this code block is called only when the authentication request ends up with 403 HTTP error.

You can temporary tweak the file C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\appengine_rpc.py as follows to see the actual reason(add logger.warn(body) line).

except urllib2.HTTPError, e:
  if e.code == 403:
    body = e.read()
    # Add a line bellow to see the actual error
    logger.warn(body)
    response_dict = dict(x.split("=", 1) for x in body.split("\n") if x)
    raise ClientLoginError(req.get_full_url(), e.code, e.msg,
                           e.headers, response_dict)
  else:
    raise

Once if you find the reason, this issue must be much easier to solve. After you solve the problem, I'd appreciate it if you could create an issue about this mysterious error message in our issue tracker?
