It's strange that preview-latex runs lualatex, which produces PDF
directly without intermediate DVI file, while it afterwards runs dvips,
which produces PS file from DVI.  Dvips is useless to use with lualatex.

At first, I thought that `TeX-PDF-mode' is disabled in that document,
but it didn't matter when I actually tried the same document with
`TeX-PDF-mode' set to nil.  Preview-latex works well for me, with the
log at the last of this message.  It invokes pdf2dsc and gs instead of
dvips, which leads to expected an image displayed in the emacs buffer.

I suspect that the preview package installed on your machine is somewhat
broken, because of the repeated "Non-PDF special ignored!" messages
recorded in your log.  That repetition doesn't appear in my log.

Maybe it would be effective for your case to deinstall and reinstall
AUCTeX on your machine.
