Public bug reported:

The python neutron client expects for the v2 API expects the neutron API
to send exceptions as a structure which has type, message and details.
While this is so for exceptions.NeutronException and
netaddr.AddrFormatError, in case of webob.exc.HTTPException  only
exception message is returned. This leads to error when exception's
'message' or 'details' attributes are attempted to be extracted in the
neutronclient session and the AttributeError in raised instead:

ash@precise64:~/devstack$ neutron firewall-rule-create --source-ip-address 10.2.0.453 --protocol tcp --action allow  /* create rule with invalid source ip address */
AttributeError: "'unicode' object has no attribute 'get'"

That's why neutron should send type and detail of an exception in the
body of a message.
