After hours of debugging with the help of charon and canton7 on the
Freenode #git channel, we found one solution for this:
1. The problem only happens on 188.8.131.52 and possibly earlier. Thus try to
find 184.108.40.206 or newer somewhere.
2. Clone the repository on --bare format with 220.127.116.11: git clone --bare
3. Try checking out bar.git using 18.104.22.168
4. Observe that everything works fine now (!)
Note that local cloning works (git clone /blah/foo.git foo) but using
file:/// or SSH protocols does *not*. So if cloning from a local path works
for you, that doesn't mean you fixed the repository, you need to try
through file:/// or SSH.
All of this is mostly relevant to Debian, since Debian stable (squeeze) at
this time uses 22.214.171.124 and testing (wheezy) uses 126.96.36.199.
I have a copy of the broken repository and might be able to put together a
list of all the (many, many!) things we tried to get to the actual root of
the problem if anyone is interested. But in general, cloning to a new bare
repository with a much newer git version could fix the issue for you.
