[web2py] GaeGoogleAccount - error ?

[Lazarof]

Hello group!
In application that worked well over a year I used:

# If running on Google App Engine
if request.env.web2py_runtime_gae:
   gluon.contrib.login_methods.gae_google_account import from
GaeGoogleAccount
   GaeGoogleAccount auth.settings.login_form = ()

Now it is returning this error:
File "/ base/python_runtime/python_lib/versions/1/google/appengine/api/
user_service_pb.py", line 236, in _CEncode
     _net_proto___parse__python.Encode return (self,
'apphosting.CreateLoginURLRequest')
TypeError: expected string or Unicode object, XML found

Please who knows about this with GAE.
Lazaro.
