I forgot to say that on this machine I have apt running as a client of apt-cacher on another machine - I've only just seen this bug report so I can't retry the upgrade to Gutsy. However, here's the relevant config file from /etc/apt/apt.conf.d:
Acquire::http::Proxy "http://valluga:3142";
Valluga is the apt-cacher host.
