g_value_set_object() increases the reference count of v_object (the GValue holds a reference to v_object ). If you do not wish to increase the reference count of the object (i.e. you wish to pass your current reference to the GValue because you no longer need it), use g_value_take_object() instead.

It is important that your GValue holds a reference to v_object (either its own, or one it has taken) to ensure that the object won't be destroyed while the GValue still exists).

If you want the GValue to hold its own reference to v_object , use g_value_set_object() instead.
