  How can I get the number of references (or variable which holds it)?
  [I don't want to set it manualy to zero :-) I want it for debug purposes]

 So I need somethig like: g_print( "ref count now is: %d", dialog-> /* HOW
TO GET REF COUNT?*/  );
 [or may be I should use "gtk_trace_referencing( )"?]
