Hi Mathias,

I think the bug is related to G1042 (partition mode binarization). It also causes the problem reported in ticket #254. I tried to fix it. However, I didn't find right text of the binarization. I think the binarization was proposed by Samsung but the code seemed from HHI. Maybe the author could provide a fix for it.
