Solved my own problem, but thought sharing would be good... Apparently it was not the content_type
call that was ignored. What happens is that Apache does an add_output_filter_by_type on each
call to ap_set_content_type (which is the Apache equivalent of $r->content_type). Output
filters are however never removed... So if you have (like I did) an output filter for a specific
type then this happens:

	$r->content_type('my/type');	 # content_type set AND output filter added
	$r->content_type('text/html'); # content_type changed, output filter REMAINS

I don't know if this behaviour is as one would expect and it certainly is not a discussion
for this list (as it is standard Apache behaviour) but worth to know...

Thanks Frank W. for sharing your thoughts.
