Comment 2 for bug 1368462

Here's what we see from the CLI...

nicira@Ubuntu1204Server:/opt/stack/python-congressclient$ openstack congress policy rule create classification "p(x) :- q(x"
ERROR: openstack Bad Request (HTTP 400) (Request-ID: req-cdfdd7e7-19e5-4da6-8d40-4391ca235c21)

Here's what we get from curl. Notice that we get an informative error message: "Syntax error for rule::Parse failure..."
