[pdftex] pdflatex 1.20a png failure

[Karl Berry]

A user reported that pdflatex in TeX Live 2004 fails on certain .png
files with "bad adapative filter type".  Perhaps it's been fixed since
(I seem to recall something about libpng updates), but I don't have an
easy way to check, so I'm just reporting it.

Since the .png file is quite large (8mb), I've put it at
ftp://tug.org/private/tmp/coyoteBrush2.png.

The LaTeX file is trivial:

\documentclass{article}
\usepackage[pdftex]{graphicx}
\begin{document}
\includegraphics{coyoteBrush2.png}
\end{document}

The transcript looks like this:
