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 pythonmagick 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
pythonmagick           from testing    0.9.19-6
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.
