Considering how this patch made it into Gnome without noticing the
distro specific requirements, especially noting these lines that should
have raised a red flag or at least an eyebrow:

+#define FIREWALLD_BUS "org.fedoraproject.FirewallD"
+#define FIREWALLD_PATH "/org/fedoraproject/FirewallD"
+#define FIREWALLD_IFACE "org.fedoraproject.FirewallD"

I'd say complaining to GNOME devs probably won't make much difference. I
know no one's perfect, but I wold have thought that their patches
underwent a little more scrutiny and required some level of review
before inclusion.

Anyway, am I correct in assuming the easiest fix would be a to point the
printer configuration launcher (correct terminology?) in gnome control
center to point to system-config-printer?

Title:
  The printing panel shouldn't display errors about firewalld not
  running

Status in GNOME Control Center:
  Confirmed
Status in “gnome-control-center” package in Ubuntu:
  Triaged

Bug description:
  It appears a patch was added to Gnome back in July that requires FirewallD to be running in order to add a network printer.
  see: http://mail.gnome.org/archives/commits-list/2011-July/msg09761.html 

  This only appears to affect those using the Gnome 3 desktop environment, and this problem is not present in Unity, so you can still add the pinter in Unity's control panel, but users wanting to use Gnome will encounter this. The specific error message is:
   "FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall." 

  The documentation in the mentioned patch suggests this behavior is
  actually intentional. However, FirewallD is, as far as I know,
  specific to Fedora.

  1) release: Ubuntu Oneiric Beta 2 (64 bit, but others likely to be
  affected)

  2) issue is more specific to the Gnome 3 desktop environment as a whole, although there may be individual packages that can be patched to circumvent this behavior
    
  3) I expected the previous behavior of being able to add a network printer without having a package that does not even exist for Ubuntu

  4) I got this nice error message that tells me "FirewallD is not
  running. Network printer detection needs services mdns, ipp, ipp-
  client and samba-client enabled on firewall."

  As far as a solution goes, a documented work-around may be a good idea
  (such as an FAQ entry that says simply to install the network printer
  in Unity), at least until a more permanent solution can be found.
