I've forwarded the issue to Debian. I also found what looks like some relevant changes in the upstream project but it's in C rather than python, and the version number differs from what Debian carries so that may be just inspirational rather than a usable change. But hopefully it gives some strong clues. See the linked debian bug for that.
