Could there be a potential security hole in providing an error response? (Not that I see it, but many problems in the past had been caused by helpful responese.)

Hi OAuthers,

My apologies if you already discussed this.

When OAuth server received unknown response_type, how should the server handle the error?

1. Show the error to the user without redirecting back to the client
2. Redirect back to the client including the error in query
3. Redirect back to the client including the error in fragment

Since choosing 2 or 3 is impossible in this case, 1 seems reasonable for me.
