Starting meteor gives TypeError: Cannot set property './template.logs.tpl.js' of undefined

I’m suddenly getting the Error TypeError: Cannot set property './template.logs.tpl.js' of undefined while starting the app (meteor npm start).
Although I restored the last version of my app (which was working), the error still occurs. I’m wondering for that because this module (log) doesn’t exist in this last working version. So I think I have to reset or delete some caching files or something like that…

I’m using the last version of meteor (1.4.2.3)
