        Ah - good catch; thanks for that ! :-)

        Right - lots of other people will hit this no doubt.

        Sounds very sensible. Just one minor complaint: - I loathe the
implementation of gtk_check_version - its impl. is as clear as mud, it
returns an non-translated string not a boolean etc. etc. ;-)

        Any chance of a tweak to use:

GParamSpec*
gtk_widget_class_find_style_property (GtkWidgetClass *klass,
                                      const gchar    *property_name)

        To see if that property is there by name ? which would make that
perhaps more readable in future ? We'd need to use GTK_WIDGET_GET_CLASS
to get the class. Hopefully with that we can get it into
libreoffice-3-5-2 :-)

        Many thanks !

                Michael.
