In addition to the workaround suggested in #90258, there is another potential cause, after rebooting and looking at the problem new, when I did a ps awux |grep cyclops (my username is cyclops of course) then I found that bonobo-activation-server was still running after logout. I then used root to login so that no processes from cyclops should be active after logging out of the gdm session.
I found that this process, bonobo-activation-server was running as well as gpg-agent.
Now, killing gpg-agent did NOT cause b-a-s service to die. so after killing it manually I then logged into gdm again and ran Synaptic, searched for gpg-agent, found it, removed it.
Now, I logged out again, used root as before, found it was still running. Killed it, killed b-a-s, logged in again, then back out again.
Repeated the login to root and search for processes, I only found a gconf process. Skeptical, I didn't kill that process but I did log into gdm again, no notification error.
It appears that in addition to the evolution-data-server problem, gpg-agent also causes a problem in having bonobo-activation-server shut down.
I have also noticed nothing out of the ordinary with evolution since doing the workaround from the other bug report.
