ubiquity crashed with TypeError in __new__(): object of type 'NoneType' has no len()

[Micheal McCarver]

Installing alongside Xubuntu Natty, importing my 11.04 account settings, and the installation claimed to be finished; I was then quickly switched to a live disc session and thrown the crash notice. When I received the message about the installation being finished, I was currently on the web based IRC launched through the link in the ubiquity installer. When I attempted to launch a second tab in Firefox, to navigate to another web-page, the installation finished message popped up, then everything started shutting down and I found myself in a live disc environment with the crash notice.
I immediately logged in here, so I have not rebooted; as is required for the ubiquity bug reporting guidelines.

It appears this is apparently connected to the terminal window font size issue that was suggested as a duplicate when I was whisked away from the desktop to here. I had not read the UbiquityDebug,txt file where is clearly states the problem is the window size, which was the issue with the suggested bug report. Sorry to waste time, resources, and perhaps someone's patience.

Keep on keeping on, and know that I thoroughly enjoy Xubuntu and will always jump at the chance to contribute in anyway possible. I had a great time testing 11.04. Though I never did encounter any problems, I would have liked to. :D
