I've filed a new bug report concerning the delayed logout ("session manager must be in idle state"): #1013548 (https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1013548).
Funnily enough, the same logout problem exists when using a different window manager (KWin in my case), but KWin is restarted properly on next reboot/login. You might mark yourself as affected there as well...
