AgileToolkit OAuth add-on error 500 at facebook's mobile site

Description:

I am using the OAuth Facebook controller add-on for ATK4.

• It works as expected when authenticating with Facebook from a regular desktop browser.
• It works when authenticating using a mobile browser that is telling face book that it's a desktop browser.
• It does not work when Facebook detects a mobile browser and redirects to m.facebook.com/dialog/oath.

What's more, is that it works fine for signups from mobile browsers (ie, when Facebook asks the user to give permission to the app).

The login flow stops with an Error 500 at: https://m.facebook.com/dialog/oauth?redirect_uri={my_url_encoded_landing_page_where_the_OAuth_controller_lives}&scope=email&client_id={fb_app_id}

What the hell is going on here? There isn't some difference between the Facebook mobile service and the regular one that the addon isn't taking care of, or is there?

This bug report can be closed: the issue is not with the ATK4 add on. I am able to reproduce the issue using FB's example PHP using their PHP API crap. It's a setting somewhere or something else undocumented. Again, this bug report can be closed.
