Thanks for debugging. In the past, the python-mpv testsuite has indeed be somewhat flaky and we didn't run the aforementioned `test_write` test for a while because of that. I've added some more info upstream, but I don't believe this is really problematic for the debian package, so I'll patch out `test_write` again until it's fixed upstream.
