[lltx] LuaTeX 0.66 segfaults when loading graphicx in LuaLaTeX

[Ulrik Vieth]

I am using LuaTeX 0.66 from TLContrib on top of TeXLive 2010.
The following minimal test file for LuaLaTeX crashes with a segmentation 
fault:

\documentclass{minimal}
%\tracingall
\usepackage{graphicx}
\begin{document}
\end{document}

Console output:
