Bert, thanks for the offer to help.

So Nova uses this FaultWrapper middleware (https://github.com/openstack/nova/blob/3b2895b960630934f827918d50577f9167110cab/nova/api/openstack/__init__.py#L106) to intercept all exceptions and problems so it can re-wrap them in its Fault class. I wonder if something changed that stopped calling the Fault instance. It seems like we're expecting all of the work that is causing this to happen in the Fault's __call__ (https://github.com/openstack/nova/blob/2bc8128d7793cc72ca2e146de3a092e1fef5033b/nova/api/openstack/wsgi.py#L1061) method and I wonder if something stopped calling it.

Note also that the FaultWrapper middleware *returns* the exception instead of re-raising the exception wrapped in the Fault. Could either of those (or both) be related to this problem?
