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.) */
