GtkToolbar's is_important property isn't kept in mind when glade starts

Description
Created attachment 169794 main.ui
I have an ui design which contains a GtkToolbar with several GtkToolButtons and its associated GtkActions.
If I set/unset the is_important property through the glade interface it works fine showing/hiding the label of the action. If I reopen the file, labels are not shown even if is_important is set.
Example attached.
