Unable to login to minimal build

I think this might also be related to this message:

I've been building images successfully on Wheezy for the last 6 months using:

# lb --version
live-build, version 3.0~a45-1

The image builds successfully after being configured like so:

lb config \
--architecture i386 \
--binary-images hdd \
--distribution wheezy \
--archive-areas 'main contrib non-free' \
--bootappend-live "ip=eth0:192.168.1.23:255.255.255.0:192.168.1.1 persistent" \
--mirror-bootstrap "http://localhost:3142/ftp.uk.debian.org/debian/"; \
--distribution wheezy \
--hostname bobbins \
--tasks minimal

When I boot the image I now get prompted with a localhost.localdomain
login: prompt, instead of just being dropped to the bash prompt. The
usual username/password doesn't work:
user/live
I've tried adding the live-user to my bootappend-live above and still no joy.

Please could you tell me what I'm doing wrong?
