Description: There are two different versions of tikz.code.tex in texlive-core-svn 2007.7194-1. One is located in /opt/texlive/texmf-dist/tex/generic/pgf/frontendlayer the other one in /opt/texlive/texmf-dist/tex/generic/pgf/frontendlayer/tikz . The one in frontendlayer seems to be old. Tikz ceases to work, until you remove it.


Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

Prepare a latex file, test.tex:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node[draw] {Foo};
\end{tikzpicture}
\end{document}

Try pdflatex test.tex

it will fail with the following error:

(/opt/texlive/texmf-dist/tex/generic/pgf/libraries/pgflibraryplothandlers.code.
tex)
! Undefined control sequence.
l.894 \pgfsetsnakesegmenttransformation
{\pgf@snake@mirror\pgf@snake@raise}

rename /opt/texlive/texmf-dist/tex/generic/pgf/frontendlayer/tikz.code.tex to tikz.code.tex~

try pdflatex test.tex again.

The document will be created without an error.
