Steps to reproduce the issue:
1. Open attached project.
2. Open scene named "Init".
3. In the "Hierarchy" window select game object named "Controller".
4. Add "Custom Behaviour (Script)" component if it is not already added.
5. Enter any positive value in the "Behaviour Count" field.
6. Delete that value.
7. Notice that this error message appears:

MissingReferenceException: The object of type 'SomeThirdBehaviour' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
UnityEditor.Editor.IsEnabled () (at /Users/builduser/buildslave/unity/build/Editor/Mono/Inspector/Editor.cs:587)

Actual result:
The error message dos not help to solve the problem, because it does not identify the line of code that tries to access destroyed object (double clicking on script to find the line that causes the issue does not work).

Expected result:
The error message should help to solve the problem by identifying the line of code that tries to access destroyed object (double clicking on script to find the line that causes the issue should work fine).
