And I just pushed my cleaned up fix to to master as well, thus hopefully
fixing the brunt of this bug.  Dario and others, please test this.  I
haven't yet pushed the tests, since we're not entirely sure of those,
but I think we should break them up further and push them too, once we
come to an aggreement on what and how they should test exactly.

Thanks,
João
