Hello.
Continuing my tests to have a list store with NULL values, I found that
if I try to gtk_tree_model_get_value(m, &i, INT_COL, &gv) on a cell I
didn't gtk_tree_model_set, I get a segfault :
(diacat:3974): GLib-GObject-WARNING **: gvalue.c:83:g_value_init():
cannot initialize GValue with type `gint', the value has already been
initialized as `(null)'
Program received signal SIGSEGV, Segmentation fault.

IMO it shouldn't segfault... Just return a GValue that's G_TYPE_INVALID
or similar.
Any hint about what should I do to recognize if a cell is unset (maybe
w/o a segfault, please :-) )?
Tks.
BYtE,
Diego.
