It happens with that image no matter what. I can have a html with 100 images and one bad image, I make one new html only with that image and it still has the problem. My guess is that probably a bug in a low level image decoder. My local machine has different kernel, different libs, plus I have different cpu,gpu and X11 on top so too much difference and I do not have the expertese to do aremote debug(or local)
