If there is an element with id="exports" anywhere on a page using Polymer, an uncaught exception occurs:
Uncaught ReferenceError: Observer is not defined in polymer.js line 8184

The element does not have to be a Polymer custom element, and the bug is triggered even if there are no custom elements on the page.

Tested with Chrome 39.0.2171.99 on Fedora Linux.

Minimal testcase:

<!DOCTYPE html>
<html>
<head>
  <link rel="import" href="http://www.polymer-project.org/components/polymer/polymer.html">
</head>
<body>
  <div id="exports"></div>
</body>
</html>
