Actually, if you can make a tarball of the .git directory of one of those
workspaces, and see if the bug is reproducable with that .git directory
every time (particularly when pulling a local repository), it would be
really helpful to have a reliable test case.
There's a debugging thing that would help, but it's not in your version.
It's in next as
49aaddd102aff Teach upload-pack to log the received need lines to an fd
With that commit, you should be able to do:
GIT_DEBUG_SEND_PACK=3 git pull 3>UPLOAD_LOG
and get a file UPLOAD_LOG that will show what it's doing, although there's
a reasonable chance that it'll only demonstrate that it's doing nothing
helpful, which we already pretty much know.
