How to disable Safari's new “feed://” redirection for feeds?

Question

I'm sure some people really love that new feature, but I use Google Reader so it's driving me batty. Not to mention that as a tech guy, I might want to actually view an XML feed once in a while (like for instance, Sparkle update feeds).

So how do I stop Safari from redirecting the normal XML feeds to their "feed://" pseudo-protocol?

Answer 1

Apparently, it used to be possible in Tiger/Safari 2.0 to disable this using defaults write com.apple.Safari DebugSyndicationEnabled -bool NO. (source) I cannot get this to work in Lion/Safari 5.1, however.

Your best bet seems to be to set the default feed reader (Safari → Preferences… → RSS) to something that gives you XML source.
