--- Comment #1 from Joseph Pecoraro <joepeck at webkit.org> ---
Note, this affects Web Inspector. We look at descriptors when expanding objects. When the "arguments" property getter is invoked outside of an invocation of the function it produces an error:

  js> (function(){}).bind(this).arguments
  < TypeError: Type error

So when inspector tries to show the value of "arguments" in object expansion, we encounter the errors. It is a bit unfortunate and we may want to workaround this.

  js> dir(function(){}.bind(this))
  < function () { [native code] }
      arguments: [Exception: TypeError: Type error]
      caller: [Exception: TypeError: Type error]
      length: 0
      name: ""
      __proto__: function () {
