Yeoman.io with nested prompts produces undefined error in Inquirer.js

I'm creating my first (real) Yeoman.io generator, which has some nested prompts (i.e. The answer of one prompt influences the presentation of other prompts and actions).

I've traced through my code, and on the surface it looks like I'm "opening and closing" my prompts appropriately, but at the very end of the script it looks like there's still an open readline (from Inquirer.js), and an extra onCompletion fires after the readlines have been closed.

I'm going to assume that this isn't a problem with the libraries (either Yeoman.io or Inquirer.js), it's a problem with the way that I'm prompting, or there's a different way to do what I'm trying to do.
