Here's one more data point. It suggests that the problem is due to either
Cygwin or possibly Git 1.7.9.
My Ubuntu box is actually a VM, hosted by my windows box in VMWare Player.
So, I tried using the VMWare shared folder feature, to mount the Windows U:
drive (which is physically on the WD NAS box) as /mnt/hgfs/Host-U on Ubuntu.
Then, I tried linux on the Ubuntu box, fully expecting it to fail as it
trampolined through Windows connection to the NAS box).
But, it worked fine.
So, at this point, it became likely that the problem is tied to the different
version of Git that I have on the two machines:
- On Ubuntu, git version 184.108.40.206
- On Windows, Cygwin's git version 1.7.9 (which appears to be the latest
version for Cygwin).
So, I installed Git on Windows from http://git-scm.com/download/win. Git
Triumph: Git on windows works with this git but, on the same file and repo,
fails with Cygwin git.
So, either something relevant changed in Git 1.7.10, or (more likely) this is a
Jason, are you also using Cygwin git? Are you also using a WD NAS?

If referring to me, then yes but it was too big for the list.
