Well, it might be more than one problem. I do get the same message if I
download the image and open it with C-x C-f. The buffer shows the raw
data instead of the image. But Emacs remains responsive and I can just
kill that buffer.

But eww causes Emacs to enter some infinite loop where C-g does not
work. The CPU load is high and Emacs keeps eating more and more RAM. The
minibuffer is flickering and keeps showing the same message.

Kind regards,
