XFCE session won't logout when Virtualbox is running

Description

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.
