       destroyed too.  But for some reason, the EActivityHanlder GtkObject
       gets freed, while its CORBA object counterpart is still an active
       server.  So there is a slight chance that we receive CORBA
       invocation that act on an uninitialized object, and we crash.  (See
       #8615.) 

       The CORBA invocation on the dead object only happens because we
       ::unref the BonoboConf database server in the ::destroy method of
       the shell.  Since this is a CORBA call, it allows incoming CORBA
       calls to happen -- and these get invoked on the partially
       uninitialized object.

       Since I am not 100% sure what the reason for this half-stale object
       is, I am just going to make sure that no CORBA ops happen in
       ::destroy...  And this is achieved by placing this call here.  (If
       the DB is disconnected, there will be no ::unref of it in
       ::destroy.)  */
