Activating Debian menu in Xubuntu XFCE

Aufter installing crossover office and not finding its menu entries, I did this:

   update-menus

This will create/overwrite ~/.config/xfce4/desktop/menu.xml And then I added those lines in ~/.config/xfce4/desktop/menu.xml:

 <separator />
 <menu name="Debian" icon="debian">
  <include type="file" src="menudefs.hook"/>
 </menu>
 <separator />

It is however better to put the lines above in /etc/xdg/xfce4/desktop/menu.xml, so they are not overwritten after a call to update-menus.
