But the fact that the warning message happens even when a max_gradient is
given by the user is still a bug, isn't it ? Or am I confused about the
purpose of the warning ? Like JRG I was a bit surprised to see my current
scene output hundreds of (useless in this case) iso warnings...

Well, thanks a lot, warning level 0 works.
I'm still wondering at the difference between -GW (turn console display of
warning text off), and WL0 (turns off all warnings), though... -GW should
work, at least, since it's working for #warning, or am I (again) totally
confused by what the text streams mean ? It's true that I never spent much
time investigating this part of Povray as it seemed quite straightforward.

As explained in my response to JRG only the output of 0.0 is a bug.  For
details about the message and relating changes, see the thread 'beta 8' in
p.pre-beta.

No, as I noted in my previous response to JRG, there is a problem.  In short
lets just say POV-Ray does not expect any text stream outputs after
rendering is complete and it would reset the user settings prior to
releasing memory of the scene.  However, that is exactly the time when
isosurfaces check the maximum gradient and output it if necessary...

I had a quick check to see if this had been fixed in beta 10.

The reported problem has been fixed, but the output doesn't look
anything like cacti any more. It looks like there's something wrong with
the camera.

It's the new camera.. just:
#version 3.1;
camera {...}
#version 3.5;
and it works fine.
