I'd say it's related to policykit. Is the process
/usr/libexec/polkit-gnome-authentication-agent-1 running in your
session? It's launched by gnome-session, i.e., when running the full
GNOME desktop.
An alternative applet is available in the form of wicd, from the EPEL
repository.

You can in the case of the window manager, at least. Using gconf-editor,
See the gconf keys under /desktop/gnome/session/required_components. You
can change the windowmanager key to a value of your choice. Also, you
might try leaving the value of the filemanager key blank. I don't know
whether that will result in no file manager being launched, or whether
it will revert to the default. Maybe the value /bin/true will achieve
the desired effect?
As a last resort, you could just tell nautilus not to draw desktop
icons. Once you start gnome-panel, then you've loaded the GNOME
libraries, GTK libraries, GLib, bonobo, etc., etc. Running nautilus in
the background will involve little additional overhead.

Hopefully it won't come to that!
