I got an error after i updated the version of three.js from r150.1 to r151.3. It said something like this:

THREE.WebGLProgram: Shader Error 0 - VALIDATE\_STATUS false  
Program Info Log: Vertex shader is not compiled.  
VERTEX  
ERROR: 0:373: ‘uv2’ : undeclared identifier  
ERROR: 0:373: ‘constructor’ : not enough data provided for construction

I don’t quite understand why this error occurred, cause I didn’t use shaders to render my model.  
Here is a demo running normally with version r150.1 [threejsr150 - JSFiddle - Code Playground](https://jsfiddle.net/VictorFang1214/znvx68pe/)  
and the demo with errors [threejsr151 - JSFiddle - Code Playground](https://jsfiddle.net/VictorFang1214/L069woe7/2/)

I haven’t found a feasible solution yet, hoping someone could help me find a way out.  
MANY THANKS!!!

Do you mind reporting this at the GitHub repository? This could be a regression.
