Comment 10 for bug 1192704

According to singon-ui the followin URL is called: https://account.app.net/oauth/authenticate?client_id=M2nq4J9PJSWjtnxkpFNJZ9kA9Z9jUQxU&redirect_uri=https://app.net&response_type=token&type=user_agent&scope=basic stream write_post follow public_messages messages

This seems fine according to the documentation" http://developers.app.net/docs/authentication/flows/web/

But it still says: "Error: Please contact the website that sent you here and let them know that there is a problem with the authorization URL."

Sadly, it doesn't show anything else. Any tips to debug this?
