Error when pop the page with a PullToRefresh

[Liuthx]

react-native: 0.39.2 When I pop the page with a PullToRefresh, It shows the error: 'Cannot read property 'removeListener' of undefined', like this:

code in TimedAnination.js, line 96:

  componentWillUnmount() {
    if(this.triggerBindID) {
      this.state.scrollY.removeListener(this.triggerBindID);
    }
  }

should I modify the code link this, and what should I do next?:

  componentWillUnmount() {
    if(this.triggerBindID) {
      this.state.scrollY && this.state.scrollY.removeListener(this.triggerBindID);
    }
  }

Sorry about the late reply, can you post a little more code of what you're doing when you're popping? I can't reproduce the error.

I only pop the navigator stack: onPress={()=>{this.props.navigator.pop()}}

Here is a demo. https://github.com/Liuthx/ptr_bug_test
