Sorry I forgot to mention that this is now in the normal apt.pg.o
build environment (chroots without any funky permission restrictions).
I have not tried Docker yet.

I think it was not happening before the backport of the Docker fix.
But I have no idea why this should have broken anything, and why it
would only happen like 3% of the time.
