Got the following output from using the newrole command on Fedora 12.
Not sure where to properly report such bugs.

If it helps, the rubix_remote_client_r role transition should fail (as
it does) as there are no role transition rules for it. The role is
associated with the current SELinux user.

I believe my system just updated to the newest newrole package.
