Comment 3 for bug 1124432

I was unable to reproduce this with a daily build from the 15th, and unfortunately your logs don't quite have enough information for me to debug it from them. Are you in a position to try installing again? If so, could you use the "Try Ubuntu without installing" option and then run "ubiquity --debug" from a terminal to start the installer (just beware that your password will end up in the debug log when running in debug mode, so don't use a valuable password)? That should make /var/log/installer/debug rather more useful.
