        I'm guessing you updated the parent type in the
bonobo_x_type_unique, but in your class init you do something like:
  
        parent_class = gtk_type_class (bonobo_object_get_type ());
  
        it is best to use:
  
#define PARENT_TYPE BONOBO_TYPE_X_OBJECT
  
        And remember to change both instances of the parent type to use   
this macro to avoid the problem in future.
  
        If you chain erroneously to bonobo_object->finalize / destroy
instead of the BonoboXObject stuff you get problems like this. If you come
up with a nice way of providing a warning, please let me know. The
headache is due to providing so much bin-compat.
  
        The finalize should not be called except when the embedded
CORBA_Object hits 0 ORB refs:

        Try eog-collection-view.c (class_init):
