Problem with gnome-cups-manager and cups 1.2

[Werner Lehmann]

Dear Sirs,

I would like to report the following problem with gnome-cups-manager:
I installed gnome-cups-manager from the 6-stable-packages, which also 
installed cups-base-1.2.2 as a dependency.
I configured cups properly and it was possible to configure my printer 
using the webinterface, but not with gnome-cups-manager.
When starting the application and becoming administrator, in "Step 1 of 
2: Printer Connection", no detected printers are shown. The real problem 
is that when clicking on "Use another printer by specifying a port" and 
clicking on the Forward-Button in order to reach the "Step 2 of 2: 
Printer Driver"-window, in the "Manufacturer" drop-down menu nothing can 
be selected, the menu just remains grey.
Therefore you cannot configure your printer using gnome-cups manager.
When configuring your printer through the webinterface, later it also 
appears in gnome cups manager, but it is never possible to configure it 
through the "add printer" procedure, as descibed above.

I know that this problem appears only with the new cups version 1.2, 
with the older cups version gnome-cups-manager used to work fine.

When starting gnome-cups-manager from a terminal the following is displayed:

# gnome-cups-manager

(gnome-printer-view:882): GnomeUI-WARNING **: While connecting to 
session manager:
Authentication Rejected, reason : None of the authentication protocols 
specified are supported and host-based authentication failed.

** (gnome-printer-view:882): WARNING **: IPP request failed with status 1030

** (gnome-printer-view:882): WARNING **: IPP request failed with status 1030


Maybe this information helps.

Thank you very much.

Regards,
