struct _GdaClientClass {
        GObjectClass parent_class;
                                                                                
        /* signals */
        void (* event_notification) (GdaClient *client,
                                     GdaConnection *cnc,
                                     GdaClientEvent event,
                                     GdaParameterList *params);
};

I mean the event_notification signal on the GdaClient class. Just
connect to it, and you'll get your callback called for the error. You
can see the code that does that in gda_connection_new, which calls
gda_client_notify_error_event to notify the listeners of the errors
occurred while trying to open the connection.
