Thank you for your interest in this bug.
The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Jaunty Jackalope. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
