OK thanks for the info. 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.
