I get this error..

It seems to be that the error is in the script section. Any idea what this is?

I'm on Mac OS X 10.10 (Yosemite) running Python 2.7.8.

The mouth of a C block has to be a list, not a Script.

(Scripts are just lists of blocks together with a position; and you can't position the contents of a C block mouth independently of the parent script!)

In [4]: s.parse("""
when green flag clicked
forever
  if (key right arrow pressed?) then
    show
  end
end
""")

In [6]: s.scripts[0]
Out[6]: 
kurt.Script([
    kurt.Block('whenGreenFlag'),
    kurt.Block('doForever',  [
        kurt.Block('doIf', 
            kurt.Block('keyPressed:', 'right arrow'),
            [
            kurt.Block('show'),
            ]),
        ])])

Hope that helps :)

Ahh okay. Thanks! :)
