I tested by applying this simple patch to e-shell.c, moving the
bonobo_activation_active_server_unregister() call from impl_finalize()
to notify_no_windows_left_idle_cb():

And lo and behold, it works! Now the ESHell gets unregistered, and when
starting Evolution again it manages to register its EShell and contact
the already running e-d-s etc.

OK to apply this patch to HEAD and stable? ChangeLog entry:

2006-06-17  Tor Lillqvist  <tml novell com>

	* e-shell.c (impl_finalize): Don't call
	bonobo_activation_active_server_unregister() here, it's too late,
	the EShell Bonobo object has already been deactivated and its
	associated CORBA object is NULL.
	(notify_no_windows_left_idle_cb): Instead, call
	bonobo_activation_active_server_unregister() here, when the EShell
	Bonobo object is still fully active.


I should still of course also investigate why the other (unknown)
mechanism which causes unregistration to happen anyway on Unix doesn't
work on Windows...
