Thanks for fixing this bug.
Alessandro, Nicolas, could you agree on who is taking this fix for
the next -rc cycle ?

I've just collected the tags and asked to Andrew if he can take it.

The point of tags is that you collect them by doing:
`git log | grep Reported-by: | sort | uniq -c | sort -rn` to see if you
are the winner. It gives me an unfair advantage if you get creative
with David's tag.

The commit being fixed went in through my tree, so I'll take this one if that's
not a problem.
