Bug#1001368: pygobject: autopkgtest needs update for python3.10: fails on output to stderr

[Paul Gevers]

Source: pygobject
Version: 3.42.0-2
Severity: serious

Dear maintainer(s),

We are in the transition of adding python2.10 to the supported Python 
versions [0]. With a recent upload of python3-defaults the autopkgtest 
of pygobject 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
pygobject              from testing    3.42.0-2
all others             from testing    from testing

I copied some of the output at the bottom of this report. It seems that 
the test ran successfully but wrote a warning to stderr. By default 
autopkgtest fails on that, which can be prevented by adding the 
allow-stderr restriction. Please prevent the warning and/or add the 
restriction.

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 Python2.10, it may help to identify what needs to be updated.
