I'm also experiencing this problem with Kubuntu-Dapper: it uses constantly about 40% CPU and produces the same .xsession-errors.
I don't know, what has been the cause, because a reboot would probably fix it again; killing gam_server does not: it gets restarted and produces the same errors.
I'm using a vanilla kernel (2.6.16.11), because of hibernation.
