Did you submit it as a pull request? That seems to be how this upstream
takes in code.

They didn't fix it in 3 months, sure. But it wasn't clear from the issue
that you had an actual fix (I certainly missed that the first time through
when I only looked at the github and not at our bug database). I'd try
submitting a pull request and see what happens. I'd also send an email to
mm@ telling him about the pull request and asking when he'll have time to
look into integrating it or commenting on it. If he won't have time to get
to it soon, I'd make the commit referencing the upstream pull request so
the next person who imports things will notice if they tweak it before
accepting the request.
