The above is a transcript of a test session.  Installing python3-numpy breaks
the "semanage port -a" command, and removing it (but not removing the
dependencies it dragged in) fixes it.

Ideally this should work, and it needs to be fixed in testing if the same bug
is there (so far I've only tested on stable).  If we aren't going to backport
a fix to stable then this bug should be left open for the benefit of users.
