Bug#343539: the daemon doesn't start after upgrade

[Mark Robinson <mark@zl2tod.net>]

Found it.

After the upgrade both /etc/cups/cupsd.conf and /etc/cups/cups.d/ports.conf 
contain the line

	Port 631

It is assumed that each appearance of this line causes the daemon to attempt to 
grab the port, the second resulting in failure.

Removing either one restores operation.

all the best
