Starting an app in an LXD type container may fail due to not finding the dbus bridge socket

I have installed Terminator in my LXD based container, and it fails to start with the following:

(terminator:165): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Failed to connect to socket /run/user/1000/libertine/dbus-s8wkkpog: No such file or directory
Traceback (most recent call last):
  File "/usr/bin/terminator", line 118, in <module>
    TERMINATOR.create_layout(OPTIONS.layout)

    window, terminal = self.new_window()
  File "/usr/share/terminator/terminatorlib/terminator.py", line 192, in new_window
    terminal = maker.make('Terminal')
  File "/usr/share/terminator/terminatorlib/factory.py", line 94, in make
    output = func(**kwargs)

    return(terminal.Terminal())

    self.titlebar.update()
  File "/usr/share/terminator/terminatorlib/titlebar.py", line 113, in update
    title_font = pango.FontDescription(self.config.get_system_prop_font())
  File "/usr/share/terminator/terminatorlib/config.py", line 371, in get_system_prop_font
    '/desktop/gnome/interface/font_name')
glib.GError: No D-BUS daemon running

Seems the /run/user/1000/libertine bind-mount is not being set up before the application launches.
