Sorry, I assumed that if the image was constantly updated (`docker pull' always gives me some news), then it is up-to-date. I now tested not with `master', but at least with something newer than a March version and the bug is not reproducible there. So, apparently this is an old bug and should be closed.

I will complain to the image maintainer instead.

Well, that looks pretty similar to mine... but it's referring to
a1Fa3d24, which is a version from March? Can you try testing with the
current trunk instead?
