[Python-modules-team] Bug#914331: python-django: autopkgtest needs update for new version of python3-defaults: FutureWarning: Possible nested set at position 1

[Paul Gevers]

Source: python-django
Version: 1:1.11.16-3
User: debian-ci at lists.debian.org
Usertags: needs-update
Control: affects -1 src:python3-defaults

Dear maintainers,

With a recent upload of python3-defaults the autopkgtest of
python-django 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    3.7.1-2
python-django          from testing    1:1.11.16-3
all others             from testing    from testing

I copied some of the output at the bottom of this report. The change in
python3-defaults made python3.7 the default python3.

Currently this regression is contributing to the delay of the migration
of python3-defaults to testing [1]. Of course, python3-defaults
shouldn't just break your autopkgtest (or even worse, your package), but
it seems to me that the change in python3-defaults was intended and your
package needs to update to the new situation.
