[Python-modules-team] Bug#975087: python-msgpack breaks python-pynvim autopkgtest: times out after 2:47 hours

Dear maintainer(s),

With a recent upload of python-msgpack the autopkgtest of python-pynvim
fails in testing when that autopkgtest is run with the binary packages
of python-msgpack from unstable. It passes when run with only packages
from testing. In tabular form:

                       pass            fail
python-msgpack         from testing    1.0.0-4
python-pynvim          from testing    0.4.1-2
all others             from testing    from testing

I copied some of the output at the bottom of this report. The test times
out after 2:47 hours (instead of the regular 1 minute run).

Currently this regression is blocking the migration of python-msgpack to
testing [1]. Due to the nature of this issue, I filed this bug report
against both packages. Can you please investigate the situation and
reassign the bug to the right package?

On top of that, due to the additional stress on our infrastructure, I'll
also block the python-pynvim autopkgtest until this bug is marked fixed
(or when I'm contacted otherwise).
