__init__() got an unexpected keyword argument 'project_id'

Finally got devstack to install up to the end w/out errors (I think) and I got 21 screen sessions (screen -x stack). Am using Ubuntu 12.04 LTS + devstack all-in-one hardware.

From the horizon debug (screen2) it seems get a successful login but just can't get pass this error...

This is the exception line and looks like request.user.tenant_id is missing...

>     c = nova_client.Client(request.user.username,
>                            request.user.token.id,

>                            http_log_debug=settings.DEBUG)

How do I troubleshoot this pls?
