The offending commit just enables using quite a few of the newly added code before that. So the problem could be in any of the newly added code. Unfortunately I can only look at this during my limited time in the evening and I have to setup my system to compile and run this, so I won't be able to get to the bottom of this as fast as I'd like to.
