I've installed this patch.  BTW, Emacs really shouldn't crash due to
Lisp code, which means there was also a bug in the C code, which I've
also fixed.  Thanks!

BTW, I noticed that you also can't view images over ssh/tramp
(ange-ftp works fine, with the above fix).  When I do `C-x C-f' to an
ssh server, e.g.,

   /address@hidden:~/barber.png

the image doesn't display.  When I look at the raw data, it looks
different from that of a local copy, so it looks like this is a
problem with Tramp rather than the image handling code.  I think there
is some trouble reading binary files off ssh/tramp.
