Comment 25 for bug 1662544

OK, so I was able to reproduce this ... kinda.

I ran the python3 version, and got the same error message.
I then installed the python2 version from the fedora repositories. It pulled in a few dependencies which I did not immediately note. Ran the python2 version and did not see the error message.
I then ran the python3 version again, and the error message was no more.

I think there is a python2 library still lurking somewhere.

I'll do a little investigation
