Ubuntu and other distros run the openssh SSH agent in addition to
gnome-keyring-daemon's SSH agent. I guess they do this for console
sessions and the like?

I have made the following change for gnome-keyring-daemon which should
help things:

The user can disable the gnome-keyring SSH agent with
gnome-session-properties [1]. If the user does this the SSH_AUTH_SOCK
environment variable should no longer appear in the list returned by
org.gnome.keyring.Daemon.GetEnvironment().

Cheers,

you have to select a different item after checking a box.
