[STR Closed w/o Resolution]

No, this patch is bogus.

Showing remote printers does not require an open Port 631 - that is only
required to share printers with other systems.

CUPS browsing happens on UDP port 631, which is bound when Browsing is On
and either of the BrowseLocalProtocols and BrowseRemoteProtocols lists
CUPS (which is the default configuration on all operating systems).

If I was to guess at a cause, look at Ubuntu patches to CUPS and/or to
firewall settings that would be blocking UDP port 631 when the scheduler
is not configured to share printers.

This is not a CUPS bug.
