You are using g_object_get(), so I suppose the integers are stored
in the instance, not in the class (and consequentially the
finalize method refers to the instance finalization).

I always free dynamic stuff (included allocated memory) in
dispose(), not in finalize(), protecting it from double calls.
There you should have a still valid instance to query.
