<debug target crashed> error when selecting date in <input type='date'>

问题

I have the following simple .dart and .html files

.dart

//import 'dart:html';

import 'package:polymer/polymer.dart';

/// A Polymer `<main-app>` element.
@CustomTag('main-app')
class MainApp extends PolymerElement {

  @observable DateTime today = new DateTime.now();
  @observable String aDate = '';

  /// Constructor used to create instance of MainApp.
  MainApp.created() : super.created();


  void onChangeFired() {
    print(aDate);
  }
}

.html

<!-- import polymer-element's definition -->
<link rel="import" href="../../packages/polymer/polymer.html">

<link rel="import" href="../../packages/paper_elements/paper_input.html">

<polymer-element name="main-app">
  <template>
    <style>
      :host {
        display: block;
      }
    </style>

    <input type='date' value='{{aDate}}'
     on-change='{{onChangeFired}}' id='time' class='margin-lb5px'>

  </template>
  <script type="application/dart" src="main_app.dart"></script>
</polymer-element>

Running the app in Dartium displays the calendar dropdown. However, each time I select a date, the application crasshes (exits) after printing the selected date with the following

2005-02-08 (:1)
<debug target crashed>

Nothing else is displyed in the console.

I created a new new polymer-app using Stagehand with the same result. Nothing else is there in the application.

This problem is present in the last two Dart Dev updates - I am currently using Dart 1.9.0-dev.9.1 (rev 44018) with the same result.

I am using the Dart eclipse plugin on Windows 8.1

Thanks

This is an issue in the Chrome version Dartium is built on.
Hopefully with Dart 1.15 we get the updated Dartium where this issue should be fixed.
