gnome-session-properties is quite broken

In an effort to workaround the lack of "Save Current Setup" check box on logout - which I understand has already been reported - I checked the "Automatically save changes to session" checkbox in gnome-session-properties to save my current desktop. And voila! On my next reboot my desktop looked like I wanted it to.

But to my dismay and disbelief this workaround introduces yet another bug which I have not specifically seen reported. After making sure my desktop was as I wanted, I then unchecked the "Automatically save changes to session" checkbox. But on the next login I was presented with an open gnome-session-properties window AND an open Nautilus. Neither of these was open when I logged out.

This behavior does not happen when the "Automatically save changes to session" checkbox is checked, only when unchecked. I don't wish to leave this check box perpetually checked nor do I wish to have gnome-session-properties and Nautilus open up every time I log in. But it now appears I am stuck with one or the other.

This is 100% reproducible on 2 different machines.

Note: the original reporter indicated the bug was in package 'gnome-session2'; however, that package was not published in Ubuntu.
