    Handle destroy callbacks of type other than GDestroyNotify
    
    It's not necessary that a destroy callback is literally of type
    GDestroyNotify - we can handle any 'void (*function) (void *)'
    
    So instead of checking against the type of the callback to
    see what to skip, look for a callback that was previously used as
    a GDestroyNotify for another callback.
