I just realized that my patch actually only fixes the gnome-cups-manager, but not the printer dialog in gnome applications - at least not in firefox.
On a related note - I posted the same information to the gnome bugtracker (http://bugzilla.gnome.org/show_bug.cgi?id=170673), and was informed that libgnomecups is currently unmaintained :-( So, it guess it's up to either the ubuntu or debian package maintainers to fix this :-( -- PPD Download broken for printers found via browsing https://launchpad.net/bugs/52867 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
