What causes the Openid error: Received "invalidate_handle" from server

I'm new to openid, and I am getting an "invalidate_handle" and I have no idea what to do to fix it.

I'm using django_authopenid

openid.invalidate_handle is the Provider's way of saying that your RP is sending an association that does not exist or has expired. The RP is supposed to respond by deleting that association handle so it isn't reused in the future. If you're always getting invalidate_handles in the response, then the RP you're using has a bug in it.
