Google Plus Api create a public profile - google-plus

Question

Hi I an issue trying to implement the google plus Api for non google plus accounts. I followed the code samples from the google developer site. In trying to authenticate a user i noticed that if you cancel/deny the creation of a google plus profile it gives a blank screen with a url "https://plus.google.com/up?continue=". If i reload the page i am giving the create google plus profile dialog , and upon cancelling again presented with a blank screen. I want to be able to let user's cancel and be returned to my site.
