Comment 6 for bug 885808

It affect me too. Actually it happens if I switched between users during uptime. Once I try to shutdown this message show. An additional issue is that I can switch between user normally, but if I have 2 users logged in and I log out with the actual one I can log in to the other but the desktop will never load in.
Please let me know what logs should I send and how to find/produce them to help bugfixing.
