Comment 1 for bug 99199

Crash reports on the installer go right here, and I find them much easier to process as a general rule than other ubiquity bugs. Please use the crash reporting tool! I really do pay attention to it.

Could you run 'sudo apt-get update; sudo apt-get install ubiquity' from a terminal window before starting the installer, and see if migration-assistant still hangs? It should be a lot better now.
