I tried with Oneiric Beta 1 released on Sept. 1rst (http://releases.ubuntu.com/oneiric/) and I can not reproduce the problem. ubiquity-dm and ubiquity started and worked as expected.

Then, on the live session, I upgraded python-gobject and python-gobject-cairo to 2.90.3-1 and ubiquity crashes with the trace in this report.

Current daily (20110903) is also broken
