Thanks for the report! I am no longer able to reproduce this issue on
'master' after 3ee9355e2fd2d0fcee1076ca1160ba5881b73da8. I'm not
entirely sure why, though :-)

So, this occured again after the core-updates merge. I managed to work
around it by changing "python-pytest" to "python-pytest-3.0", which is
very odd.

There is a race condition lurking here somewhere, but I built with
"--rounds=10" after both "fixes" without problems.
