Steps to reproduce:

Create a new project
In the Project window, right-click in the Assets folder
Select Create > Scripting > MonoBehaviour Script
Name it QANull
Replace its contents with the script below and save it

using UnityEngine; [ExecuteAlways] public class QANull : MonoBehaviour { public static QANull Instance; public event System.Action Changed; void OnEnable() { Instance.Changed += Noop; } void Noop() { } }

In the Hierarchy, create an empty GameObject
In the Inspector, click Add Component
Search for QANull and select it
In the Console, select the NullReferenceException entry

Actual results: The stack trace does not contain QANull.OnEnable; it starts at engine frames:

NullReferenceException: Object reference not set to an instance of an object.
UnityEngine.GameObject.Internal_AddComponentWithType(Type)

Expected results: The stack trace starts at QANull.OnEnable () (at Assets/QANull.cs:7), as in 7000.0.0a1

Reproducible with versions: 7000.0.0a5, 7000.0.0a8

Not reproducible with versions: 6000.7.0b4, 7000.0.0a1
