Well, tried it again with latest git and it happened, however 1.2.2
did not produce that issue.

It is not really that easy to provide a recipe, as a lot of different
things were tried and only the downgrade made any difference. And now
that I moved back to git master it works again as it is supposed to,
so even I can't reproduce it.
