paper_selector's margins not functional

["Robert Roebling" <robert roebling de>]

  Hi,

there is a bug in 2.8.0. I'm trying to
use the gnome_print_paper_selector with
margins. I can only correctly change the
margins if the units chosen are point,
otherwise the dialog displays the values
in that unit, but the value is stored
as points nonetheless. Since the dialog
even uses centimeters as the default
unit to use for displaying (German locale)
this makes the dialog (at least the margin
part) unusable for now.
