I have gotten the same error while trying to install Feisty Fawn Beta i386. I have made two separate downloads, burned two cds and checked mdsums. I got an error message saying that ubiquity had crashed and tryed twice to send a bug report from wthin the installation desktop but I have no way of knowing if they got through. I have been able to install and use the beta kubuntu feisty fawn but I haven't been able to get past this point installing this beta nor was I able to save anything in the way of documentation. I wondered if the program is confused by the number of versions of Linux installed on these drives.

Thanks for your report. This is also bug 95400, and is fixed in current versions of Feisty.
