Yes. It turns out that was exactly what was happening but I had no idea where the second registration was coming from. Using a custom "addObserver" method revealed the culprit.

I'm trying to log messages to track down a really pesky messaging bug where a KVO observer's "observeValueForKeyPath" class is always called twice whenever the observed object's "pageNumber" property changes. I googled around a bit and found that you can enable message logging by enabling "NSObjCMessageLoggingEnabled."
Is it possible you're seeing two calls to observeValueForKeyPath because one observer instance has actually been registered twice?
