[Debian-med-packaging] Bug#972528: ctdopts: incompatible with Python 3.9

[Michael Hudson-Doyle]

Source: ctdopts
Version: 1.4-1
Severity: normal
Tags: upstream

Dear Maintainer,

The autopkgtests fail with Python 3.9. It appears to be a simple fix
which I have already proposed upstream.

Cheers,
mwh
