CentOS 5 :: Administration --> Printing Dialog Freezes Centos 5.6

if I choose Administration --> Printing and then try to select a printer from the list of available printers (to delete a printer for example), the dialog
freezes and needs to be terminated forcibly. It seems like I can hit "New Printer" and add a printer without anything freezing. All of the printers on the list are
network printers.

Possibly related- if I use evince to view and document and then attempt to print by going File --> Print, it gives me a printer selection box which also freezes if I try to choose a printer from the list.
