When I upgrade to Intrepid after the release, I'll test that. However, I doubt whether any fix to apt-cacher can fix this bug, since apt-cacher is behaving correctly. It's update-manager that doesn't correctly handle APT's configuration option Acquire::http::Proxy. The proof is that when sources.list is modified to force use of the proxy, update-manager works.
