For your convenience, I have now set up a Git repository where you can
get slightly updated versions of the above scripts. The Gitorious web
page is here:
http://git.lysator.liu.se/ceder/git-clone-fail-demo
You can clone it like this:
git clone git://git.lysator.liu.se/ceder/git-clone-fail-demo.git
I have been able to reproduce the problem on Git 1.6.0 as well, so
this is apparently not a recent regression.
The problem can also be reproduces when you clone, push and fetch via
ssh, but it happens a lot less frequently then. See the README file in
the git-clone-fail-demo repository for info on how to reproduce it.
