After trying to bisect this using `bisect start; bisect good v1.5.1; git 
bisect bad HEAD; git bisect run ..test.sh`:

---test.sh---
#!/bin/sh

make clean
make || return 125
GIT=$(pwd)/git

cd /tmp
rm -rf testrepo
mkdir testrepo
cd testrepo
$GIT init
echo test > test.txt
$GIT add test.txt
$GIT commit -m "Add test.txt"
$GIT bundle create ../testrepo.bundle master || return 125
cd ..

rm -rf testrepofrombundle
$GIT clone testrepo.bundle testrepofrombundle || return 1

I was unable to find a bad revision.
After a lot more searching I found that I had `git` aliased to `hub`, a 
tool used to make Github actions easier.
Eliminating `hub` from the equation resolved most problems.
The only ones remaining are the confusing error message from `git bundle 
create` and the "missing HEAD" (you can interpret that in different 
ways) ;-)

P.S. I hereby promise to _never_ _ever_ alias `git` to something else and 
then post a Git bug about that "something else" on this ML.

Sorry to have wasted your time,
