Diederik, I tried to understand what's happening but without looking into the code. If you want, take a look at what I wrote on Bug #398715 (which is another one related to this issue so can be marked as duplicate).
Maybe those considerations can help you.
I still think it's a wrong formula somewhere.

Good work.
