Trisquel 6? That's a bug in that version of GNOME Fallback, not a mistake you
made. GNOME Flashback doesn't even offer an option to have no panels; the
last remaining one can't be deleted.
The problem resolves itself if you log out and log back in. It doesn't happen
in the version of GNOME Flashback on Trisquel 7.

Have you ever tried GNOME Shell before? I get the impression that you
haven't. Most of the initial flak the GNOME team got when GNOME 3 was
released was because it's designed with "limited flexibility, but a more
idiot-proof GUI", in a sense (you can pretty much change everything, but this
is done with extensions you write in JavaScript, not configuration settings).
