IIRC there where some changes in the pdf processing code of pdftex in
latest release, but only there. So I can't see, how the png-part
could be affected.
However, could you try to downgrade to tetex-bin 2.0.2-22? It should
be sufficient to just download the deb-file, unpavk it using dpkg-deb
or ar and put /usr/bin/pdftex into the actual directory and then call
./pdftex filename.tex
does that cause the same segfault?

So it seems a valid file.

Well, just valid LaTeX code.
