We got an empty response back from bugzilla; don't know why, having the response code would be helpful.

We could also retry the request.

Start in apis/bugzilla_api.py at commentOnBug, then trace its caller in components/bugzilla.py. Check how the response is handled when JSON decoding fails, and verify that the Bugzilla response code is available in the resulting error; retry behavior is also suggested but not defined.
