Oops, should have included those.
It seems to be stochastic indeed. For example using this:
tests/using-intree tests/run-all tests/tests/quilt-gbp-build-modes-sbuild
tests/tests/sbuild-gitish
means only sbuild-gitish fails.
I can get them both to fail by doing just
tests/using-intree tests/run-all
I don't want to post those whole .log files publically, so here are some
extracts:

The Debian buildds switched to the "unshare" backend and sbuild will default to

To start using "unshare" add this to your `~/.config/sbuild/config.pl`:

If you want to keep the old "schroot" mode even in the future, add the

Looking at my sbuild config, there isn't anything that should be
relevant. I think that for me too everything that the test suite should
depend on is in /etc. And I've been successfully using the dgit test
suite for some years.
