Better fix for the problem causing Critical assertions in gtk_adjustment_set_value/page_size and g_object_freeze/thaw_notify. These resulted from calling gtk_databox_set_total_limits() in gtk_databox_init().  Setting only the box->priv->total_* led to a nasty bug caused by translation_factors being calculated to infinity values, resulting in no graphs being shown.  By setting box->priv->visible_* also to a rational default, everything works better.  This is not the definitive fix.  Should figure out why translation_factor got screwed up in the first place.
