[keycloak-user] Keycloak 3.3.0 fails Google Social Registration with NPE

[Niels Bertram]

I unzipped Keycloak 3.3.0.Final and configured a localhost:8080 instance
realm "play" to use Google Identity Provider for sozial. Navigating to
http://localhost:8080/auth/realms/play/account will get me to the login
page as expected, then I click on the Google logo and it takes me to google
login. Login is all good but then I get back to the Keycloak server and I
see this stack trace in the web browser and logs.

Anynone seen this before? I got exact setup behind a proper DNS with SSL
and it works fine. In the "Play" realm I configured Require SSL to none and
cant really think of any other thing that could cause this. Anyone seen
this error or has any suggestions for configuration?
