I am able to reproduce this both on a live system and within HyperV vm.
1. Try Xubuntu
2. Install virtualbox: $ sudo apt-get update $ sudo apt-get install virtualbox virtualbox-ext-pack
3. Run virtualbox: $ virtualbox
4. Logout: $ xfce4-session-logout -l
The result is that the virtualbox process ends, but the system does not logout!
I couldn't find any logfiles, or systemd-inhibit entries that seems relevant. I've no idea where to look next.
