The only settings I have in my hgrc are:

[paths]
default = https://vim.googlecode.com/hg/
default-push = git+ssh://git@github.com:amadeus/vim.git

As stated in the title, Mercurial 3.1 and hg-git 0.7.0

[sunshowers]

This appears to be repository corruption inside your .hg/git store. I'd suggest recloning.

[apayne]

I've had the same problem, but hg verify shows the repo as clean. Could we instead do this?

cd .hg ; rm -rf ./git ./git-*

I've got a similar issue:

pushing to git+ssh://git@git.overlays.gentoo.org/user/triquetra.git
