the problem is that get_row_data is not for retrieving the row's data,
as returned from the DB. For that, you use the GdaDataModel being
displayed by the grid (gnome_db_grid_get_model). get_row_data is for
retrieving the user data associated with the row, which apps can set
with gnome_db_grid_set_row_data. It is just for allowing apps to
associate extra data structures with each row.
