    atspi_accessible_dispose: Avoid unreferencing NULL
    
    The children array may contain NULL entries, when the children have not
    all been inspected yet for instance.  In such a case
    atspi_accessible_dispose's call to g_ptr_array_free would warn out when
    freeing array items with g_object_unref.  We should thus check for NULL
    to avoid such warning.
