> It seems to be because Emacs tries to open the .art file in image-mode.
> The regexp seems to be added by imagemagick-register-types.
>
> Removing .art from auto-mode-alist works.  The following workaround will
> remove the complete regexp, that is, all extensions added by
> imagemagick-register-types.
