Cannot read property 'contexts' of null (Workaround here)

[seanmorris]

Using Babel 0.5.0 (with brunch) with the following config:

exports.plugins = {
  babel: {
    'presets': ['es2015'],
    'env': {
      'production': {
        'presets': [['minify', {

        }]]
      }
    }
  },
};

Will produce errors like the following:

17:25:50 - error: Compiling of app/article/component/HeadingMenu.js failed. TypeError: app/article/component/HeadingMenu.js: Cannot read property 'contexts' of null

Disabling "builtIns" stops this error:

exports.plugins = {
  babel: {
    'presets': ['es2015'],
    'env': {
      'production': {
        'presets': [['minify', {
          'builtIns': false
        }]]
      }
    }
  },
};

I am experiencing the exact same problem, and the suggested workaround works great, but is there any way I can do that from the cli?
