I don't think this is a bug, username must begin with a character 
(unless you created the user using NIS or adduser --force-badname).
# Default from /etc/adduser.conf
# check user and group names also against this regular expression.
#NAME_REGEX="^[a-z][-a-z0-9_]*\$"

From adduser man page:

      --force-badname
               By default, user and group names are checked against the 
configâ
               urable regular expression NAME_REGEX  (or 
NAME_REGEX_SYSTEM  if
              --system is specified) specified in the configuration 
file. This
              option forces adduser and addgroup to apply only  a  weak 
 check
              for validity of the name.
