The texi2pdf command which runs pdftext is built against the wrong version
of the libpng library. The error states 1.0.6 while the RPM is 1.0.8 and
libpng detects this a dies.
This is a standard 7.0 release with the one texinfo.tex upgrade which is a
rather nice upgrade (hint hint).

Reproducible: Always
Steps to Reproduce:
1. Get the lastest texinfo.tex from
    ftp://ftp.gnu.org/gnu/texinfo/texinfo.tex
   and replace in
    /usr/share/texmf/pdftex/texinfo/pdftexinfo.tex
2. Create a simple PNG image called test.png using gimp.
3. Create the texinfo as stated in the additional info section below.
4. Run `texi2pdf test.texinfo
	

Actual Results:  $ texi2pdf test.texinfo
