This can't be fixing it, the default is commented out.

I wonder if this is a locale specific problem.  Can you try (in a
chroot, whatever), installing haldaemon with a default config for
adduser to try to reproduce it?  I am curious if it will succeed if you
then set LANG=C and install it again.  I suspect it will install.  If
this is the case, can you let me know?

Cheers,
