Yes, it seems to have been compiled with imagemagick support. I don't have 14Gb of ram :-)So, the problem is then that this is not any kind of image. It's a text file (actually a
program for http://art.kano.me, which expects coffeescript). If I run:
convert Identify nelson.artimagemagick tells me that I have a 26708x29472 1-bit ART image, which explains the problem!
It loads normally if I rename the file not to have the .art suffix. So I can solve my immediate problem.
It's not clear to me whether imagemagick is making a real mistake here. it doesn't seemto do any significant checking on the image header: https://github.com/ImageMagick/ImageMagick/blob/7ce65e7125a4e1df1a274ce373c537a9df9c16cd/coders/art.cHowever these old formats often didn't include any redundancy anyway.
However it does seem like any filename ending in .art is a bit dangerous for emacs at the moment.

Alex, was your Emacs compiled with Imagemagick support? Mine wasn't,
so visiting that file does nothing special.
