Bug Description
Binary package hint: gnome-session
Karmic alpha x86_64 on a ThinkPad X61 Tablet.
gnome-session 2.26.1-1ubuntu1
gconf2 2.26.2-1ubuntu1
dbus 1.2.14-2ubuntu5
metacity 1:2.27.0-0ubuntu2

After switching from "None" to "Normal" in the Visual Effects tab of the Appearance preferences, gnome-session goes into a tight loop adding and removing a client, via dbus, which causes gconfd-2 to use an extraordinary amount of CPU time.
To reproduce, set your effects to none, log out, log in, set effects to normal, and watch in top(1) to see processes spinning.
Logging out and logging back into the session stops that behavior.
I will attach traces from strace and dbus-monitor.
This bug affect me too but I don't know what I did to set it off. It is using 180-190% of my dual-core cpu, and it's sleeping.
