Bug with adding network printer (IPP) in Gnome 3?

[Andrew Wood <a j w me com>]

Is there a bug with adding a new network printer (IPP) in Gnome 3 
because I am unable to do it in both Fedora 15 (Gnome 3.0) Fedora 16 
(Gnome 3.2) and Debian Wheezy (Gnome 3.0).
There seems to always have been a bug that prevented you from adding a 
printer using its DNS hostname, Ive always had to put in the IP address, 
but in Gnome 3 even when you enter the IP and click search, when the 
printer make/model comes up, clicking the Add button cuases System 
Settings to hang.

Is anyone else aware of this problem?
