We don't want the font buttons created by the inspector to run on the
default display.
font_button->font_dialog = gtk_font_chooser_dialog_new (font_button->title, NULL);
gtk_window_set_hide_on_close (GTK_WINDOW (font_button->font_dialog), TRUE);
gtk_window_set_modal (GTK_WINDOW (font_button->font_dialog), font_button->modal);
+ gtk_window_set_display (GTK_WINDOW (font_button->font_dialog), gtk_widget_get_display (GTK_WIDGET (button)));
font_dialog = GTK_FONT_CHOOSER (font_button->font_dialog);
