Comment 7 for bug 1678486

Neal: We're using our own implementation, although it's talking to the same XML-RPC backend. I don't know whether the code would get very much shorter if we refactored it to use python-bugzilla; it would still need to fit into our framework for external bug trackers, so it wouldn't surprise me if there ended up being a bit of an impedance mismatch.

Anyway, all of the things that I've identified as going wrong so far (and fixed in my attached merge proposal) are specifically to do with translating Bugzilla's view of the world into something compatible with the Launchpad data model, so an external library wouldn't be able to help here.
