Detaching <select> results in an exception

[goj]

Hi,
I have the following html:

    <button ng-click="attached = !attached">Toggle!</button>
    <div ng-if="attached">
      <select ng-model="irrelevant">
        <option>foo</option>
        <option>bar</option>
      </select>
      </div>
    </div>

Clicking the button, selecting "foo" and clicking a button again results in the following error:

The null object does not have a getter 'ngValue'.

NoSuchMethodError : method not found: 'ngValue'
Receiver: null
Arguments: []

With the following stack trace:

#0      Object.noSuchMethod (dart:core-patch/object_patch.dart:42)

This has probably something to do with _inputSelectDirective.expando[_attrs.element] being set to null in OptionValueDirective.detach().
