ubiquity crashed with AttributeError in on_advanced_button_clicked()

[Igor Lopez]

Binary package hint: ubiquity

During install from Live CD with Kubuntu Jaunty Alpha5 AMD64 ubiquity crashed when returning from the advanced option just before install should start.
I did deselect the install of startmanager since Grub is already setup and handled by my other Ubuntu install.
