templates by iron router. it happen every time when it's switching from a template that use famousEach to any other template

Exception from Tracker recompute function:

This is my code using famousEach

layout.jade

template(name="layout")
  +Scene
    +HeaderFooterLayout
      +Node id="tab" position = "[ 0, -300 ]"
        +Node position = "[ 0, 5 ]"
          +DOMElement
            img(src="/images/logo.png", width='250')
        +TabMenuLayout position="[ 300, 0 ]"
          +famousEach menuItems
            +Node 
              +DOMElement
                a.tab(href=url)
                  h3
                    | #{title}
      +Node id="content"
        +yield

posts.jade

template(name='Posts')
  +Node id="posts"
    +GridLayout id="grid"       
      +famousEach posts
        +post                                                 


template(name='post')
  +Node
    +DOMElement
      .center-block.text-center.post-item
        a(href="{{pathFor route='posts.show' data=this}}")
          .loading-bg
            img.img-circle(src='{{thumbUrl imageId isVideo}}')
          h4 {{title}}
        a.user-link(href="{{pathFor route='users.show' data=user}}")   
          em By {{user.username}}

I was trying to find out the problem with debugging,
In meteorFamousView.js, I found that child.blazeView is undefined, when it's iterating, when child is pointing famousEach

MeteorFamousView.prototype.destroy = function(isTemplateDestroy) {
  var fview = this;

  if (isTemplateDestroy && fview._destroyPrevented)
    return fview._destroyPrevented();

  log.debug("Destroy (start) of " + this.type + " (#" + this.id + ") from " + this._source + ": children, components");                                                                                              

  // TODO, tests
  _.each(this.children, function(child) {
    //child.destroy();
    Blaze.remove(child.blazeView);
  });
......

I'm not sure if it's a bug or I'm using famousEach wrong way.
