Could be related to
https://github.com/NixOS/nixpkgs/commit/64a072e3576daae794712d898efe0fa0f44075a0.
I think that's the commit that changed the fetchgit hash on master
(and it was not backported to stable). So these days you have to be
careful when backporting a Nix package using fetchgit from master to
stable.
