I've run into this myself.
This is the result of using outdated WSGI startup scripts. As part of
your upgrade process, you must switch to the ones from the release
you're trying to deploy.
This is because keystone has refactored some responsibilities out of
those WSGI scripts, so your scripts are now redundant with what Keystone
is trying to do.
