ubiquity hangs indefinitely at Step 6

[Brian Murray]

Binary package hint: ubiquity

Using ubiquity version 1.6.5 on an Edubuntu 2007-10-09.1 Desktop CD the installer has stopped functioning. It is still open and the little wheel is still spinning but nothing is happening. Additionally, update-notifier has indicated that a crash report in ubiquity was detected. However, that crash report was not uploadable due to another bug. During the installation process I choose to import information from an account on a different partition into an account named brian and at the "Who are you?" step I also set my account name to brian. I found the following in /var/log/installer/debug:

Ubiquity 1.6.5

I have been able to reproduce this multiple times.
