Upon a successful installation of the latest Oracle Virtualbox using the existing Lilidog installer, the Mate authentication agent may no longer enable properly on login.

This will cause both gparted and synaptic to fail to show the authentication dialog when selected either from the menu, and the right-click 'Open as Root' in Thunar... simply won't. There are others as well, but if those won't open, you know you have this issue.

The current fix is to add to $HOME/.config/openbox/autostart:

/usr/libexec/polkit-mate-authentication-agent-1 &

and then log out and back in.

New releases with this addition already added will be out in a couple of hours. This is the only change right now, but sure will cause an issue if you don't know how to fix it, and a lot of people want to use Virtualbox.
