I don't know what trigger this error, in my configuration (even in
minimal one, see below) the sample document is typeset just fine.

I didn't see nothing suspicios, only the message with lua error, I
didn't see it in terminal and in Emacs.

Last try, could you make a backup of your ~/.emacs file and use attached
one to test your system (Emacs+AUCTeX). Just
1. make a copy of your original ~/.emacs;
2. change it's context to the provided one;
3. start new Emacs session;
4. open a test file and
5. do C-c C-c on it. Be sure that you choose the "ConTeXt" target.

Besides that check the *Messages* buffer, may be you find something
unusual there.
