In system-config-printer as it comes with Oneiric (1.3.6) it is no problem to enter '@' and ':' in the host name field for LPD printers and in the "Enter URI" input field. I Have tried
lpd://till:till@192.168.2.106/
in enter URI, selected a driver, and let system-config-printer generate the queue and this URI actually appeared in /etc/cups/printers.conf. And the printer actually prints.

So at least for Oneiric this bug is fixed.
