renderer.compile throws "Cannot read property 'state' of null"

[LinoPhil]

Describe the bug

Hi THREE Team,

in my viewer I load meshes at runtime. To reduce stuttering I call renderer.compile after new meshes/materials where added to the scene. Everything worked fine till 131.

Now compile crashes with:
three.module.js:26024 Uncaught TypeError: Cannot read property 'state' of null
at getProgram (three.module.js:26024)
at three.module.js:25554
at Mesh.traverse (three.module.js:6982)
at Scene.traverse (three.module.js:6988)
at WebGLRenderer.compile (three.module.js:25542)

To Reproduce

You need a scene with:

1. scene.environment = textureCube; // where textureCube is a simple 6 jpg cubemap
2. while the scene is running.. animationloop add a new mesh with multimaterial
3. call renderer.compile on the scene
