Debug.js:41 TypeError: isNaN is not a function

Hi,

I am trying to use the 1.3-module-7 with npm install material-ui --safe
(I use also the flow-router)

I think it may have something to do with SSR, but I am not sure.

Everytime I try to use a material-ui component I get the following

Exception from Tracker recompute function:
debug.js:41 TypeError: isNaN is not a function

I found someone how know the solution:

Removing the wallaby.js fixed this issue !

Thanks, you saved my day!
Any additional information on the exact reason is welcome.
For now, I just renamed the wallaby.js file.
