Bug#584967: live-helper: machine boot fails to add default user

[Marco Stronati <youfind.marco@gmail.com>]

Package: live-helper
Version: 2.0~a14-1
Severity: important

The configuration of the machine is the following:

lh config --apt-recommends false \
  --mirror-bootstrap "http://ftp.it.debian.org/debian/"; \
  --mirror-chroot "http://ftp.it.debian.org/debian/"; \
  --mirror-binary "http://ftp.it.debian.org/debian/"; \
  --archive-areas "main contrib non-free" \
  -b usb-hdd -a i386 -k 686 -d sid -p "standard" \
  --packages "firmware-linux-nonfree" \
  --bootappend-live "locale=en_US.UTF-8"

lh build gives no errors but when I boot the image with qemu I got:

[...]
Begin: Adding live session user ... pwconv: failed to change the mode of /etc/passwd- to 0600
adduser: Only one or two names allowed.
chpasswd: (user ) pam_chauthtok() failed, error:
Authentication token manipulation error
chpasswd: (line 1, user ) password not changed
The default user (user) is not present,
no other valid users found, disabling autologin.
done.
[...]

And I cannot log in the system. I solved by using the interactive 
shell to manually add a user.
Thanks for the great software.
