Hi Paolo,

Another week, another very small pull request. This time, the bug is
irritating enough that I want it fixed and backported right away. It
has only been found by inspection (thanks Will!), but once you've seen
it, you can unsee it.

If you haven't pulled the previous tag [1], you'll get both for free.

Please pull,

	M.
