Did this and still no success. I made all attempts to make sure that 
there  is not something wrong in my altered config.status, but all 
checked out o.k. As much as I can see, GDB shows the crash occuring in 
gdataset.c  (glib-2.2.3at the location):

gpointer
g_datalist_id_get_data (GData     **datalist,
            GQuark     key_id)
{
  g_return_val_if_fail (datalist != NULL, NULL);
 
  if (key_id)
    {
      register GData *list;
     
--->      for (list = *datalist; list; list = list->next)
    if (list->id == key_id)
      return list->data;
    }
 
  return NULL;
}

As I trace the program, this function is visited many, many times, looks 
like "list = list->next" may be assigning an unaccessable address. I am 
downloading Version 4.0 and will test tomorrow. Please suggest further 
what to do.

yours
Richard
