Hi Chris, I am no longer actively using Kubuntu on a physical host. I do have a virtual image of Kubuntu 12.04 that I occasionally use, but I have not faced this issue on that.
I regret that I am unable to help you further with the testing for this issue. Feel free to close this bug.

I am returned to the login screen with compositing automatically disabled. The second and further logins work. I have to manually enable compositing by going into System Settings -> Desktop Effects. This has started affecting me only since Oneiric.
