I see something new, which is probably also not good.

I opened an image with emacs -Q, turned on auto-revert-mode, edited the
image externally with an image editor, saved there to the original file,
and then emacs asked "[image file name] changed on disk, really edit the
buffer?  ".  Here is an image of the backtrace (an image because I used
SIGUSR2 to get a backtrace, and after that, Emacs is gaga - is
there a better way to get a backtrace for a y-or-n prompt)?

I used v from dired to open the image file if it matters.
