Hello...
This code works fine for some time.... but crashes anytime with the
following log....
Gtk-CRITICAL **: gtk_list_store_get_value: assertion `VALID_ITER
(iter, list_store)' failed
GLib-GObject-CRITICAL **: g_object_set_property: assertion `G_IS_VALUE
(value)' failed
GLib-GObject-CRITICAL **: g_value_unset: assertion `G_IS_VALUE (value)' failed
I am trying to reuse the same GtkTreeView....
