This looks like it might be a separate issue with a missing getElementsByTagName("img")[0] in

    // is there an inner image?
    if (linkName.length == 0 && actedOnItem.getElementsByTagName("img")) {
      if (actedOnItem.getElementsByTagName("img")[0]) {
        if (actedOnItem.getElementsByTagName("img")[0].hasAttribute("src")) {
          linkName = actedOnItem.src.split("/").vfGaLinkLast();
        }
      }
    }
