This almost all works fine (there are some annoying intermittents
which mean that most of my full test runs fail somewhere for some
reason, but they aren't issues with this pullreq as far as I can
see[*]), but...

This seems to happen reliably with this pullreq merged

This should work fine if you retry this PR after having merged Fam's PR
which contains the fix.

I guess Travis is using a cached image.

Cool. I will do that and retry.

I'm not using travis, this is a local run of the test.
But perhaps my system has a cached image. It seems a bit
odd that it uses that cached image when testing master
but not when testing Paolo's merge, though.

The patch "test: replace gtester with a TAP driver" contains docker
changes (adding libtest-harness-perl) which trigger a rebuild, your
builds using /master should use the cache.

This might be a problem with this new package (if so, Fam's PR isn't
going to help here).

I'll check and if possible improve the docker.py output to get a more
useful error message.

Regards,

Phil.

Yes, in some versions of Debian it's a virtual package.  I should just
install perl instead.
