Comment 17 for bug 1204919

I had the confirmation prompt turned off indeed. I turned it on, deleted saved sessions, logged out with xfce4-session-logout, unchecked the option on the confirmation dialog to save the session and the next login was fine. I shouldn't have to go through all this though, but I'm not sure were is the issue.

And actually normally I'm using the logout menu item from the "Action Buttons" applet (or whatever it's called in English), which doesn't have the new confirmation dialog with the checkbox to save the session or not. And logging out from here keeps saving the session.
