Thanks for reporting this, and so helping to make Ubuntu even better. As far as i can tell, something about the configuration of your machine apparently caused the scripts concerned to think your hostname was '04'. This is not a valid hostname, since hostnames should start with a letter.
Could you please attach copies of the two files /etc/host and /etc/hostname to this bug report?
