Question gdome test program

BlankHi,
I compile gdome using VC.
And meet a problem when running \test\bench.c

it is broken down in traversal()
because the ownerDoc is NULL after call gdome_xml_n_unref

Do you meet the same problem?

void gdome_xml_n_unref (GdomeNode *self, GdomeException *exc) 
{
    .......
   switch (type) {
    .......
  default:
........

      n->_private = NULL;
   }
}

void
gdome_treegc_delNode (GdomeNode *node)
{
  .......
 ownerDoc =  gdome_xmlGetOwner (priv->n)->_private;
 g_assert (ownerDoc != NULL);
 ownerDoc->livenodes--;
........
}
