Thank you, Jonathan!

I did not have such an older environment available, but now
could install the infrastructure and get all prerequisites 
in place for FreeBSD 9.3/AMD64 testing.

That allowed to both reproduce the original failure and confirm
that it does not occur any more with your proposed patch.
