Without further confirmation of this patch's correctness, I do not want
to add it until after the 0.2.0 branch release. I have been trying to
push that out for most of the week, but it would be good to include this
fix if it is indeed required.
Can you perhaps provide a little more explanation regarding why you
believe this patch to be correct? Sorry for having to ask, but I need
to learn the details in order to make an informed decision about it.
