Fixed - thanks!! I won't lie - I have no idea what a trailing new line is!
But as this was a test system I was testing the upgrade on, I simply moved the "squid.conf" to "squid.conf.temp" and put the default "squid.conf.dpkg" as "squid.conf" I then re ran "apt-get upgrade" and it ran without the error. "dpkg -s squid3" now thinks it's "installed ok" so I;m assuming it's all happy again. I shall work on removing the dodgy lines from our squid.conf as it is a completely custom handwritten configuration file and more than likely to have these dodgy "trailing newlines". I have to work on the squid.conf file anyway as squid upgrade has completely change the way NTLM authentication works... as it's broken on upgrade :( Many Thanks for quick response.
