It's a long-known bug (since Dapper) that the Kubuntu desktop CD installer can't handle reiserfs; this is because qtparted only supports reiserfs by means of libreiserfs, which generates broken reiserfs filesystems that cause our kernel to oops, so I had to disable that. That has absolutely nothing to do with this bug.
