Here's an alternate patch that worked for me with both CD and USB
installs, and has a fallback to the old behavior if none of the mounts
contain .disk/info. Please try it and let me know if it solves your
issue:

 # workaround for: http://bugs.debian.org/390647


As an added bonus, I think it will also fix:
