Clojurescript Build with Modules - Constants Table Crashing

Question

I'm building an app using:

lein cljsbuild once min

where my min config is

{:id "min"
 :source-paths ["src"]
 :compiler {:output-dir "resources/public/js"
            :main app.core
            :optimizations :advanced
            :modules {:app
                      {:output-to "resources/public/js/app.js"
                       :entries #{app.core}}}
            :pretty-print false}}

I end up with 3 js files: cljs_base.js, constants_table.js and app.js

When I include them in my index.html file in that order, I get a console exception:

Uncaught TypeError: cljs.core.Keyword is not a constructor at constants_table.js:1

If I add :optimize-constants false then it builds the modules correctly.
