React crash when starting application (probably my fault)

I’m working with meteor and react in some applications on my computer, but it appear I cannot create a new one. Here’s what I do :

➜  projects  meteor create helloworld
Created a new Meteor app in 'helloworld'.

To run your new app:
  cd helloworld
  meteor

➜  projects  cd helloworld
➜  helloworld  meteor
[[[[[ ~/projects/helloworld ]]]]]

=> Started proxy.
=> Started MongoDB.
=> Started your app.
=> App running at: http://localhost:3000/

Ok, everything is working. But then, I add react, and here’s what I get :

➜  helloworld  meteor add react
Changes to your project's package version selections:
coffeescript        added, version 1.0.11
cosmos:browserify   added, version 0.8.4
jsx                 added, version 0.2.3
react               added, version 0.14.1_1
react-meteor-data   added, version 0.2.3
react-runtime       added, version 0.14.1_1
react-runtime-dev   added, version 0.14.1
react-runtime-prod  added, version 0.14.1
react: Everything you need to use React with Meteor.
➜  helloworld  meteor
[[[[[ ~/projects/helloworld ]]]]]

=> Started proxy.
=> Started MongoDB.

Any lead ?

Waoh… One of my previously working project stopped working after a meteor reset. And it went back working when I restored the .meteor/local/plugin-cache/ folder.

It appears that the only thing I have to restore are the 4 .cache files in the .meteor/local/plugin-cache/cosmos_browserify/0.8.3/ folder and that I’m not able to build them properly now.

I made a full reset of node and all my npm packages with no result.

There was mention of a new meteor update having a bug - can’t find the post now unfortunately - can any on verify this? That may be the problem?
