Comment 90 for bug 868400

This generally seems to happen when two syndaemons are running. They are being spawned by gnome-settings-daemon.

Comment 69 is the case where there are two instances from the user. This could happen if g-s-d crashes and then respawns, as right now g-s-d only checks its internal variable manager->priv->syndaemon_spawned, it doesn't actually check if there is a running instance. This confirms the g-s-d task.

Comment 81 is the case where syndaemon gets started from lightdm, and keeps running in the user session. I think the best and easiest solution would be to change g-s-d gsettings in lightdm to not start syndaemon at all, it's not really necessary/useful in the greeter and just overhead.
