Strange event emitter error

[haustraliaer]

While clicking around the auth section (more than necessary as I was testing button states) I came across this odd error in the console:

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.

Cannot reproduce :/

Found a way to reproduce this, and have a thought on a fix

As you can see from my console, the wallet-opening event is being bound over and over again. We need to unbind this event when the view changes (not sure how to do this in ractive)

FYI I monkey-patched the emitter to give me some hints

var Emitter = require('events').EventEmitter

var emitter = new Emitter()

emitter._off = emitter.off
emitter._on = emitter.on

emitter.on = function() {
  console.log('Bound', arguments)
  this._on.apply(this, arguments)
}

emitter.off = function() {
  console.log('Unbound', arguments)
  this._off.apply(this, arguments)
}

module.exports = emitter
