The line in question:

this.startDialog = function startDialog(msg, timeout) {

I guess you're invoking this incorrectly? Might just be me being silly.

Any chance you're not using the "new" keyword when instantiating a Conversation?
eg:

var conversation = new Conversation(robot)

Take a look at the unit tests. npm test should be passing for all of them.

Hmm I removed all of the scripts I had and simply npm installed, giving the above error.
I think there's a clash with another package which I'm investigating now.

You're right though npm test passes and it works fine for a completely new hubot repo.

Welp, I was being dumbdumb and adding "hubot-conversation" to external-scripts.json when it was not needed. Crisis averted.

¯_(ツ)_/¯

Just FYI, I ran into this also, might be worthy of a reminder to NOT do that towards the top of README.md. Just to help us out when we're not thinking. :)

Done :)
