regression with current TeX Live packages

[Norbert Preining <preining@logic.at>]

Dear maintainers,

I see that sphinx autopkgtest fails with new texlive-base being
installed. The error is
	! LaTeX Error: Unknown graphics extension: .foo.png.
This has been the case since very long time, and loading of
	grffile
package is required.

In a simple test example I cannot reproduce the problem you are facing:

$ cat bla.tex
\documentclass{article}
\usepackage{grffile}
\begin{document}
Hello

\includegraphics{oma.foo.png}

\end{document}
$ pdflatex bla.tex
...
[1{/var/lib/texmf/fonts/map/pdftex/updmap/pdftex.map} <./oma.foo.png>]
(./bla.aux) )</usr/share/texlive/texmf-dist/fonts/type1/public/amsfonts/cm/cmr1
0.pfb>
Output written on bla.pdf (1 page, 16489 bytes).
Transcript written on bla.log.
$

Could you please show the problematic file? Could it be that the sphinx
TeX code is playing around with some internals of the graphics package,
which can result in failures due to LaTeX core updates?

Thanks

Norbert
