Marius,

A typo on my part. The code should be (towards the end):

(add-hook 'LaTeX-mode-hook
		'(lambda ()
			(setq TeX-master (guess-TeX-master (buffer-file-name)))))

add-hook is the proper thing to use, not setq. And setq doesn't like the quoted
symbol, but add-hook does.

I should test these things before replying!

Best,
