       condition that I cannot work around.  What happens is that the
       EShell object gets unreffed and its aggregate EActivityHandler gets
       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.)  */
