X-server doesn't start every time I end a session and I log in again with a new user

[giuprivite]

Binary package hint: gnome-panel

The problem reported in Summary happens to me both on two different machines: a PIV based computer and on asus notebook with an intel centrino processor and an ATI X700 Mobility Raedon graphics device (I don't remember the graphics device of the PIV system but I suppose that it is an integrated on motherboard chip).
Every time that I log-out and try to log-in again with a different user, I obtain an empty screen without any panel, or menu, or wallpaper. The only action I can do is to press [ctrl] + [alt] + [<--] (to restart x-server) and than reboot the system because even if I try to log again with the old user I always obtain the empty screen.
Thanks for you precious work, Giuseppe Privitera

Thank you for your bug. Does it work if you stop the running evolution-data-server before login again?
