Well, you could provide a Minimal, Complete and Verifiable Example
(http://stackoverflow.com/help/mcve): most likely, the error depends on
particular features of your current HEAD, or environment variables.
Because i do *not* get that error if I run `git difftool -d HEAD~`.

So it is not so much about collecting info as about distilling your use
case into an example that allows other developers to reproduce the
problem, and subsequently fix it.

Ciao,
