git push stdout is empty while the command executed successfully(status=0)

[devnetf]

repo = Repo(...)
git = repo.git
git.push() //return empty string
git.execute(["git","push"], with_extended_output=True) //the success message is in stderr_value instead of stdout.

Actually I don't think this is a problem of git-python, as the example is using the command-line wrapper exclusively. It is very dependent on the git version running on the machine.
If you have trouble with something like repo.remotes.origin.push(), the problem would possibly be with git-python though.
