Windows native emacs or emacs under cygwin ?

Would you mind to post the "confusion error message" here? Because some people may find it useful.

This feels old, we have v1.8.5.2 as the latest version.

I have access to Debian, where I can

This could be helpful:
a) compile git under cygwin (try 1.8.5.2), and see if the problem is still there.
b) Which version of cygwin do you have? 
c) If the same problem exist under Debian, debugging it could be helpfull, yes.
  If the same problem exist here, in some version of git, it would be helpful to test
  the latest version of git. (Which means compile & debug)
