xfce4-session is currently broken in another way as well, since it does not 
always restore the session, but I haven't figured out so far.

Anyway, back to your problem: Are you using Gtk 2.3? Maybe they changed the 
semantics for the window type property. Please try to verify it by 
uncommenting the line from xfce4-session/shutdown.c.
