fatal: mark :76404 not declared

I've been using git-remote-hg happily for months. However today, without having updated git or git-remote-hg, I'm unable to push or fetch or pull. Instead I get this error:

11:55 am % git fetch

fatal: mark :76404 not declared

Here's a gist with the crash dump mentioned above: https://gist.github.com/tenpn/a5bedf7680797d5657919feee5fd938a

I've updated git-remote-hg to see if that helps, and it doesn't.

Is that mark :9999 something to do with my project? Is there possibly some issue with either the remote hg or the local git repo? Or is it a bug with git-remote-hg?
