Comment 41 for bug 1611237

Hmm - we're running Neutron 9.2.0 but still having this problem:

2017-04-19 20:14:48.481 25633 ERROR ryu.lib.hub [-] hub: uncaught exception: Traceback (most recent call last):

And we definitely have the fix from this ticket when I go and look at the ovs_ryuapp.py, so it's not a case of us having a bad package.
