Menu->Configure opens the configuration file in TextEdit, which is a disaster since it has smart quotes on by default. I spent a significant amount of time trying to figure out was wrong with your json parser before I realized what was going on.
It was opened as plain text. That option is orthogonal to smart quotes, although it turns out those can be turned off globally as well. Thanks for leading me in the right direction.
I still think there must be a better way to do it for Shuttle, though, given what the defaults are. Even something as hacky as replacing smart quotes with normal ones before json parsing would be pretty useful.
