While I agree the bug you are trying to fix is real bug, the patch look
a bit messy. Moreover, as far as I know Peter is doing work in this area
and he's willing to fix the bug. You know, he's rewriting the area from
scratch (or something like that), so I don't really want to cause a
rebase conflict to him. Moreover, some tests fail after this patch, so I
will not merge this for now, sorry.
