Public bug reported: I've been running Precise since mid-Alpha 1 with no problems, I'm assuming this is some kind of weird condition with moving to the Alpha 2. Running dist-upgrade in a terminal produces a similar situation, it attempts to remove both ubuntu-desktop and unity. Apport isn't being super helpful in this situation, so let me know if there's further debug information you need.
