[Debian-med-packaging] Bug#1001410: python-csb: (autopkgtest) needs update for python3.10: TypeError: multiple bases have instance lay-out conflict

Dear maintainer(s),

We are in the transition of adding python3.10 to the supported Python 
versions [0]. With a recent upload of python3-defaults the autopkgtest 
of python-csb fails in testing when that autopkgtest is run with the 
binary packages of python3-defaults from unstable. It passes when run 
with only packages from testing. In tabular form:

                        pass            fail
python3-defaults       from testing    3.9.8-1
python-csb             from testing    1.2.5+dfsg-6
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of python3-defaults 
to testing [1]. https://docs.python.org/3/whatsnew/3.10.html lists 
what's new in Python3.10, it may help to identify what needs to be updated.
