The fix for bug/1178375
https://bugs.launchpad.net/oslo/+bug/1178375
introduces a method raise_invalid_topology_version(), which is invoked when an invalid topology version is configured.
This method is improperly called by the code - it is missing an argument. Example:
(py27)[kgiusti@t530 work (master)]$ ./my-server.py --topology=42 server01
Running server, name=server01 exchange=my-exchange topic=my-topic namespace=my-namespace
Using QPID topology version 42
