hi steve, did you ever find a solution or determine the root of this problem? i'm having the same issue running rails 4 and thin on OS X 10.6.8 in development...
for those who are experiencing the error, "ERROR: Rack::Utils::OkJson::Error: cannot encode Symbol", i suggest using the taps-taps gem instead of just "taps." that's the only changed i had to make to get taps to work (it appears taps is incompatible with rack 1.5, but i can't say for sure). thanks to the following resource for solving the problem.
