Hello,
The following test-file produces an error:
% engine=luatex
 \usemodule[chemic]
 \starttext
 \chemical{CO_2}
 \stoptext
This is tooo long.

\usemodule[chemic] is enough to produce the error with mkiv.

Replace the following lines in m-chemic

\ifx\beginpicture\undefined
  \let\normalgrid\grid
  \let\normalaxis\axis
  \input pictex.tex \relax
  \let\pictexgrid\grid
  \let\pictexaxis\axis
  \let\grid\normalgrid
  \let\axis\normalaxis
\fi

with

\ifx\beginpicture\undefined
  \let\beginpicture\relax
\fi

and the module works.

Wolfgang
