jonathan, if this is really possible with the tree model API, then it's
fundamentally broken. you should not accept a 0-type-value from the user and
g_value_init() it with a type. GValues should always be passed around
properly type initialized, i.e. treemodel should assert that the type
of the value to get is_a
G_VALUE_TYPE (value_passed_to_gtk_tree_model_get_value).

and dave, no, value.data[0].v_pointer is not valid, don't ever
access value.data directly, here you'd use g_value_get_pointer().
