Error on webkit

[Jonh Wendell <jwendell gnome org>]

Hi, folks.

I'm trying to run the example found on
http://github.com/jdahlin/gjs/blob/cairo/examples/webkit.js but gjs
gives me an error:

    JS ERROR: !!!   Exception was: Error: Unable to construct boxed type
WebView since it has no zero-args <constructor>, can only wrap an
existing one
    JS ERROR: !!!     lineNumber = '0'
    JS ERROR: !!!     fileName = 'gjs_throw'

It doesn't even run the script. It just aborts.

I'm running gjs and webkit from master.

Does someone have any hint?
