New lines in predicate causes "Could not load Choosy preference pane."
Somehow I ended up pasting a new line into what ends up in the predicate value in behaviors.plist. This causes the "Could not load Choosy preference pane." error and prevents any links from being routed. I removed the offending newline and all is well again.
