There's your reason; just to repeat it:
gdb Depends: gnome-session
gnome-session Recommends: nautilus.

That's because nautilus doesn't depend on any of those. They depend
on it.

^^^^^^^^^^^^^

No, gdm Depends: gnome-session.

Because nautilus doesn't depend on gdm; it's the other way around.
If aptitude went around installing everything that depended on whatever
you wanted to install, you'd have all of Debian on your system pretty
quickly. ;-)

Because:
gdm Depends: gnome-session
gnome-session Recommends: nautilus

Then you need to remove gnome-session and replace it with something
else.
If you want *all* the reasons that nautilus is on your system, run
$ aptitude why -v nautilus | less
and read through all the answers that you get out. (I apologize for
the lousy formatting you'll see in the process, there's already a bug
about it). e.g., on my system nautilus is also held on the computer
by gnome-desktop-environment and rhythmbox.
