I upgraded my N810 a while ago to Diablo and everything in the app manager seemed to work fine (Including updates). Now when I try to check for updates the manager reports that it's trying to access 127.0.0.1:8118 which leads me to believe it thinks it should be using Privoxy.

I've never had Privoxy installed under Diablo and as I said this used to work. Now the behaviour has changed and I don't know how to correct it.

Is there a config file I can edit to tell the app manager not to use a proxy?

Other apps such as the web browser are working fine and the connection settings aren't configured to use a proxy.
