Just got this same problem. I'm using a fresh install of Ubuntu Karmik 9.10.
could not associate with desktop session: Failed to connect to socket /tmp/dbus-JkQLeZ2Kjq: Connection refused
It then logs me out straight away. I've had that kind of behaviour several times since I got Karmik. Not sure if that would be related to the graphics card, an Nvidia, as I've got karmik in other laptops (with no Nvidia) and haven't had any problems so far.
