I'm not at all sure whether the two are related, but directly after this happened, compiz crashed hard and wouldn't restart again, and the upgrade stalled. I had to reboot, after which I found myself in unity2d. Am now trying to complete the upgrade as best I can and get back to a workable state, but it may mean a full reinstall.
