Source: circuits
Version: 3.1.0+ds1-2

Dear maintainer(s),

With a recent upload of python3-defaults the autopkgtest of circuits
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
circuits from testing 3.1.0+ds1-2
all others from testing from testing

I copied some of the output at the bottom of this report.
https://docs.python.org/3.9/library/collections.html says:
"""
Deprecated since version 3.3, will be removed in version 3.10: Moved
Collections Abstract Base Classes to the collections.abc module. For
backwards compatibility, they continue to be visible in this module
through Python 3.9.
"""
Time to move on.

Currently this regression is blocking the migration of python3-defaults
to testing [1].

Don't worry and many thanks for the patch, I'm including it right now.
