Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Steps: 1) Select "Log Out" from the panel, then select "Switch User". 2) Select User B and log in. 3) After some time log out User B. Problem: From time to time I find myself back on the login-screen and both users are logged off (with no processes of either of them left running), although logging off User B should not affect User A's processes.
