Public bug reported: I have 3 users on my system, we use the panel applet to close or suspend the session and switch to the lightdm login screen. Sometimes happens that if I switch to another user (without closing the session), going back to the previous account (via lightdm-greeter) the whole system freeze. Lightdm can open the suspended session, appears the desktop frequently with the imagine of the previuos window to suspend the session. But anything work. I have to hard reset.
