Hi Arash,

You're right, AUCTeX loads the file just fine if emacs is started with 
the -Q switch. Does that mean that there's something else in my 
configuration of Emacs (or AUCTeX?) that is tripping AUCTeX up? I 
wouldn't even know where to start looking...

In the meantime, the solution that works for me is to reduce the local 
variable list to:

%%% Local Variables:
%%% TeX-engine: xetex
%%% coding: utf-8
%%% End:

I think the line

%%% mode: latex

is the culprit in my case. Was there an infinite loop between AUCTeX 
loading latex-mode automatically and again due to the local variables?

Best,

Florian
