Your traceback shows that `six` does not cause your problem.
It is quite obvious that a `test_winreg` will want to load the
`wingreg` module.

Yes. Apparently, you run the Python test suite - and depending on
platform and available infrastructure some of its tests fail.

In my package `dm.xmlsec.binding` I use
`test_suite='dm.xmlsec.binding.tests.testsuite'`.
Maybe, you can ensure to get the correct test suite in a similar
way for your package.
