For now, I'm going to move this test to the "flaky" set that is only run
when a specific environment variable is set. As far as I can tell, it's
working correctly, and it usually takes about 10-15 seconds and passes;
but it intermittently takes more than 5 minutes, which is a timeout when
running under ginsttest-runner. I don't know whether it would have passed
if allowed more time, or whether it has deadlocked.

I'm cloning a bug for the underlying test failure, so we have something to
represent the failure mode even after the autopkgtest failure has been
avoided.

Dear maintainer(s),

I looked at the results of the autopkgtest of your package. I noticed 
that it regularly fails since around March 2022 on armel [1] and the 
first of October 2022 on armhf [2].


Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
