An error happened on the server side: #undefined

I get a popup saying this as soon as I click on "search", starting from an untouched set of your files. The browser shows "http://localhost:8000/?q=hello/" as the current url (with "hello" being the word I was searching).

http://localhost:8000/#search/hello works instead.

I am running your example on Chrome 34.0.1847.137 on MacOS 10.9.2 and the simple server.sh server you provide, running locally.
