Hmm, you need to do this, to initialize GValue:
{
GValue dctvalue={0};
/* if you want to be sure that value is initialized as G_TYPE_INT value */
g_init_value(&dctvalue, G_TYPE_INT);
}

g_object_get() doesn't accept the GValues, pass the pointer to gint instead:
{
gint double_click;
g_object_get(
G_OBJECT(settings),
"gtk-double-click-time", &double_click,
NULL
);
}
Or (if you want to play with GValue):
{
GValue value={0};
g_init_value(&value, G_TYPE_INT);
g_object_get_property(
(GObject*)object,
"gtk-double-click-time",
&value
);
/* now you can use g_value_get_int() */
}
