The backtrace already suggested, but I could not believe it.. It seems gnome-cups-add is being incredibly stupid and sending out SNMP request forever, essentially disregarding the ICMP reports flowing back from the LPR server, as the attached screenshot shows.
And gnome-cups-add is already very lucky that it receives ICMP errors; It could happen that the SNMP packets would be silently discarded by a firewall! Really, gnome-cups-add should not SNMP-probe the print server for more than a couple of seconds. PS: a friend of mine got this same problem on a Dapper system. I'm on Edgy. I didn't make this analysis on her system, but I suspect the same problem because the symptoms are the same. ** Attachment added: "wireshark screenshot of SNMP packets" http://librarian.launchpad.net/4273192/Screenshot-%28Untitled%29%20-%20Wireshark.png -- Adding LPD printer freezes gnome-cups-add https://launchpad.net/bugs/60576 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
