Hallo Emmanuele,

it's not getting better. Here's my code. li->data points to a cild of the table, and the code compiles 
without warnings with -W -Wall:

-------------------------
g_value_init(&value, G_TYPE_INT);
gtk_container_child_get(GTK_CONTAINER(table), li->data,
    "left-attach", &value, NULL); 
g_printerr("%s\n", g_strdup_value_contents(&value));
g_value_unset(&value);
-------------------------
and on running it, I still get this error:

 GLib-GObject-CRITICAL **: g_value_unset: assertion `G_IS_VALUE
(value)' failed

Strangely, when I comment-out the call to gtk_container_child_get(), g_strdup_value_contents(&value) just 
returns "0" (as expected). It seems to be gtk_container_child_get() that somehow messes up the value.

--D.
