Perhaps it is not so obvious from the title of bug #8070 that it is the same, but if you read the bug description, it is the symptoms of xfwm4 not being started. Four of the users on that bug also confirm that the cause is xfwm4 not being started, because it is no longer in the saved session file.
Apparently, xfwm4 not being started at login is the most frequently reported xfce bug in forums, but nobody has managed to track down the cause. I was just wondering if this bug might be that cause, as the symptoms (logout, "session manager must be idle" error, force close of session, no xfwm4) sound the same.
