I just got hit by this as well. The bug also triggered an Apport
dialog, which (IMHO erroneously) pointed to
https://bugs.launchpad.net/ubuntu/+source/software-
properties/+bug/1167314.
I guess the action linked from the software-properties-gtk "Restart..."
button ought to be configurable by a packaged setting. For XFCE, it
looks (by quick googling) like "xfce4-session-logout --reboot" would be
a suitable value for XUbuntu.

Title:
Restart button in Additional Drivers does not restart Xubuntu
Status in software-properties package in Ubuntu:
Confirmed
Bug description:
After changing a driver in Additional Drivers tab of Software &
Updates, a message tells me a restart ('You need to restart the
computer to complete the driver changes.') is needed and introduces a
button to restart the system. This button does not seem to do anything
in Xubuntu 14.04.2.
Upon running software-properties-gtk through terminal and then
clicking the restart button, these lines are printed:
Traceback (most recent call last):
