Changing generic animation to legacy while it is used in timeline throws "Assertion failed" error

Timeline

-

How to reproduce:
1. Open the attached project
2. Open test scene and select Eskimo_2
3. If you open its timeline playable you can notice that it uses few animations
4. Find "people" character in the project
5. Change its rig to Legacy
6. Select Eskimo_2 in hierarchy

Actual result: you should get few "Assertion failed: Assertion failed on expression: 'MecanimDataWasBuilt()'" errors
Expected result: error should be clear and state that legacy animation clips are not supported on timeline. Just how it is written in inspector under animation after you select it in timeline

Reproducible: 2017.1.1f1, 2017.2.0b10, 2017.3.0a2, 2017.3.0a6

    I am getting this error currently too. this is how I get it...

    1) I get these two warnings:
    The AnimationClip 'Idle' used by the Animation component 'Player' must be marked as Legacy.
    Default clip could not be found in attached animations list.

    2) I then make the changes it asks for and I get the:
    Assertion failed: Assertion failed on expression: 'MecanimDataWasBuilt()'

    The real problem is the warning: must be marked as legacy. which was a problem years ago but it seems to be one now as well.
