Close gnome session from console

Question

I use Ubuntu 11.10 64 bits with Gnome Shell.
I have opened a bug because sometimes "Close session" and "Shutdown" buttons doesn't work. gnome-session-quit only works sometimes: bug

How can I close the session cleanly from console without gnome-session-quit?

Solution

The following command is an alternative for the gnome-session-quit (logout) which should close the session cleanly (not killing the gdm):

dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.Logout uint32:1.

(it's one line)

It works the first time but if I cancel and I try to use it again, it doesn't work. It only shows: method return sender=:1.2 -> dest=:1.6450 reply_serial=2. I think this is related directly with the bug mentioned before.

@Simón Probably gnome-session-quit is executing the above dbus command behind the scenes so you are hitting the same bug.

well, is it not as clean as "gnome-session-quit"?

This answer doesn't work from a terminal not part of the dbus session. How do you set it up so an unrelated terminal can use another dbus environment?
