Google API Python Client OAUTH Appengine example borked?

Question

The Google API Python client (http://code.google.com/p/google-api-python-client/) has a sample application demonstrating OAUTH2 on the Google App Engine infrastructure. This can be found at:

http://code.google.com/p/google-api-python-client/source/browse/#hg%2Fsamples%2Fappengine

I tried grabbing this example, filling in the client_secrets.json with my app's credentials, but running with the local dev_appserver I get:

When I deploy the app live on GAE using appcfg.py, when I head to the root page of my app, I get a 500 Server Error, and the development console logs read:

So uhm, help?

FWIW, I did follow the instructions on copying the entire client code to the app engine project (as outlined at http://code.google.com/p/google-api-python-client/wiki/GoogleAppEngine)

I think this was fixed in http://mail.codereview.appspot.com/5593052/, but they haven't put out a new release that includes this fix, yet. Your best bet is probably to use trunk until they do.
