Latest betas break tikz matrix

23 Feb 2011

      Hi all,

This code used to compile in versions of context prior to January,
though I can't quite pin down the versions.

\usemodule[t-tikz]
\usetikzlibrary{matrix}

\starttext
\tikzstyle{description}=[fill=white,inner sep=2pt]
\starttikzpicture
    \matrix(m)[matrix of math nodes,
      row sep=3em, column sep=3em,
      text height=1.5ex, text depth=0.25ex]
           {x&y\\
             z&u\\};
    \path[->]
      (m-1-1) edge node[description] {$*$} (m-1-2)
              edge node[description] {$*$} (m-2-1)
      (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
      (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\stoptikzpicture
\stoptext

(compilation error at the bottom of this email)

I thought at first that this was a luatex problem, but I've ruled that
out with the following plain tex file, which compiles just fine in
plain luatex and in plain pdftex:

\input tikz.tex
\usetikzlibrary{matrix}

\tikzstyle{description}=[fill=white,inner sep=2pt]
\tikzpicture
    \matrix(m)[matrix of math nodes,
      row sep=3em, column sep=3em,
      text height=1.5ex, text depth=0.25ex]
           {x&y\\
             z&u\\};
    \path[->]
      (m-1-1) edge node[description] {$*$} (m-1-2)
              edge node[description] {$*$} (m-2-1)
      (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
      (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\endtikzpicture
\end

I have no idea what the error is telling me and what could be causing
it. Any ideas?

Many thanks,

Mathieu
