ubiquity crashed with RuntimeError in progress_loop()

Binary package hint: ubiquity

I got this from today's ubuntu-netbook daily image. I got as far as answering all the questions, then it crashed.

I actually got two crash reports, the first one was bug 523648. I don't know whether one is just the consequence of the other.
