are you sure, the callback is called several times? sounds like the a
callback is attached several time to me. this can happen in complex
environemnt, and you could check that very easy by checking the listeners
array of the emitter.
if the array is fine, then you can debug the code. you can inspect the the
3rd party code for something liem ".emit('eventThatCausesTroubles'" and put
some console.trace calls here and there. If its a bug a pull request is the
best issue message.
