NullReferenceException when using GrammerRecognizer (Unity 5.4)

Editor - Other

-

Steps to reproduce:
1. Download and open attached project.
2. Attach script named "GrammerErrorTest" to the main camera.
3. Make sure that "Maximize on Play" is enabled in the "Game" window.
4. Enter the play mode.

Actual result:
The play mode stops and the "Console" window outputs these four error messages:

1.
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.DockArea.OnGUI () (at C:/buildslave/unity/build/Editor/Mono/GUI/DockArea.cs:272)
UnityEngine.Windows.Speech.GrammarRecognizer:.ctor(String)
GrammerErrorTest:Start() (at Assets/GrammerErrorTest.cs:12)

2.
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.DockArea.OnGUI () (at C:/buildslave/unity/build/Editor/Mono/GUI/DockArea.cs:272)
UnityEngine.Windows.Speech.GrammarRecognizer:.ctor(String)
GrammerErrorTest:Start() (at Assets/GrammerErrorTest.cs:12)

3.
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.DockArea.OnGUI () (at C:/buildslave/unity/build/Editor/Mono/GUI/DockArea.cs:272)
UnityEngine.Windows.Speech.GrammarRecognizer:.ctor(String)
GrammerErrorTest:Start() (at Assets/GrammerErrorTest.cs:12)

4.
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.DockArea.OnGUI () (at C:/buildslave/unity/build/Editor/Mono/GUI/DockArea.cs:272)
UnityEngine.Windows.Speech.GrammarRecognizer:.ctor(String)
GrammerErrorTest:Start() (at Assets/GrammerErrorTest.cs:12)

Expected result:
There should be no error messages and the play mode should not be interrupted.

Reproduced with:
5.4.0b18, 5.4.0b24, 5.4.0f1, 5.5.0a3.

Note:
Everything works fine when "Maximize on Play" is disabled in the "Game" window.

    Yeah, I get the "No cameras rendering" message, then the

    NullReferenceException: Object reference not set to an instance of an object
    UnityEditor.DockArea.OnGUI () (at C:/buildslave/unity/build/Editor/Mono/GUI/DockArea.cs:272)

    error in the console. The game plays fine, after the first time I run it, but always this sequence of errors the first time. There is definitely a camera.

    I get this when first playing a scene from the Unity editor. It says there is no camera in the scene for several seconds before it actually uses the camera in the scene. Started happening as soon as I started using the new gui components.

    I got this when I was trying to unite a bunch of sprites to a packing tag. It did it okay then when I went to go into play mode unity crashed to desktop.
