LiveChat using example code throws "ReferenceError: LC_API is not defined" errors in production

[chrispatterson]

Working off the example LiveChat code, I am getting errors in production (though not in development mode, which I expect is because TurboLinks isn't active in development).

Error is coming from inside the LiveChat tracking.js
"ReferenceError: LC_API is not defined" tracking.js (line 2, col 15327)

    <% if current_user %>
      <script type="text/javascript">
        var __lc = {};
        __lc.license = #######;
        __lc.params = [
          { name: "Name", value: "<%= current_user.name %>" },
          { name: "Email", value: "<%= current_user.email %>" },
          ];

        (function() {
          delete(window.LC_API);
          delete(window.LC_Invite);
          delete(window.__lc_iframe_current_skill);
          delete(window.__lc_inited);
          delete(window.__lc_lang);
          var lc = document.createElement('script'); lc.type = 'text/javascript'; lc.async = true;
          lc.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'cdn.livechatinc.com/tracking.js';
          var s = document.body.getElementsByTagName('script')[0]; s.parentNode.insertBefore(lc, s);
        })();
      </script>
    <% end %>

Believe that since this is coming from the generated iframe that many users won't see it, and it seems to be working correctly from my smoke tests, but wanted to make sure there isn't an iceberg hiding in these waters.

(I don't believe this is likely to be a browser-dependent issue, but in the event I'm off-base there I am on Firefox 39, on fully-updated Yosemite)
