title: What does TypeError non_object_property_load mean?
body: <p>I see this error a bunch in javascript that I'm debugging.  In the JS console Chrome says something very similar to</p>
  
  <pre><code>TypeError
      arguments: Array[2]
      message: "-"
      stack: "-"
      type: "non_object_property_load"
      __proto__: Error
  </code></pre>
  
  <p>I can usually work my way to the underlying problem, but in general what does the error represent?</p>
  
  <p>Is there any way to get a stack trace to the line that caused the problem?</p>
