i found this in the logs underneath the error i posted above:
Facebook: Couldn't create the user account

[marafa]

just noticed the login page has this line below the php errors

Unable to create your account. Please try again.

Did you grant the Facebook application access to your email address the first time you used it? You can check in your App Settings on Facebook. I just added a nicer error message if this happens in 5ce1638

It would be nice to let the user re-auth and add the email permission as described at https://developers.facebook.com/docs/facebook-login/login-flow-for-web/v2.0#re-asking-declined-permissions but I haven't seen how to do this without an SDK yet.
