Also tested without the "..(x + w) > 8191" criterion (that is only y+height check), and still no crash. Tested website, plus a 12000x10 png and a 10x12000 png (both PNGs have transparency). And also tested with a 9000x9000 PNG (also w/transparency). I'll see if can get you the debugging-info you have requested ..
