Unfortunately, my TeXLive doesn't have a tiger. ;-)

Ah, there you go!  AUCTeX called latex.

So now I can get a similar error also with Hugo's example:

And indeed, when using pdflatex I can see that preview is loaded
(without having to usepackage it):

--8<---------------cut here---------------start------------->8---
(/home/horn/.TeX/preview.sty
Package: preview 2017/04/24 13.1 (AUCTeX/preview-latex)
\pr@snippet=\count352
\pr@box=\box78
\pr@output=\toks51
)
--8<---------------cut here---------------end--------------->8---

The error stays the same no matter if the TeXLive or AUCTeX preview.sty
version is used.

Ok, so at least we have an example now which seems to fail successfully
for most of us. ;-)  David, does that fail on your machine, too?

Bye,
