older libpng still crashes on your pngs, due to iTXT chunk with xml crap. while this is definitely libpng problem, removing iTXT chunk is a good thing by itself: in some files that chunk alone is bigger than the rest of the data!
p.s.: this report is for binary built from source on my GNU/Linux, of course, not for official binary.
Crap, is that because I shipped it with png lib 1.2? I can build with libpng 1.6 instead. Probably be another few hours until I have some time to do it.
