[lltx] Fail to compile documents with lualatex

[Yan Zhou]

Dear all,

I am trying out TeX Live 2010 pretest. I tried to compile an old document with lualatex. It compiles perfectly with pdflatex, but with lualatex, it fails. Below it the error message.

! LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.429 \begin{document}


It looks rather strange. Luatex stop at the line of  \begin{document} but complain that \begin{document} is missing. Is there any extra setup steps needed for luatex?
