git bisect finds
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/commit/ce0e898fb476df740a1c337ac9910f504251c466
as the faulty commit:

commit ce0e898fb476df740a1c337ac9910f504251c466 (HEAD, refs/bisect/bad)

    libnm: refactor caching of D-Bus objects in NMClient


I'm bringing Thomas into the loop here.

The failing NM tests that are run by python-dbusmock are available at
https://salsa.debian.org/python-team/modules/python-dbusmock/blob/master/tests/test_networkmanager.py

Thomas, is that a regression in NetworkManager or does python-dbusmock
need to be updated?

Regards,
Michael
