[Bug] React.createElement: type is invalid -- expected a string (for built-in components) or a class/function

[thehappycoder]

It works fine in 1.3.4 but fails in 1.4.0:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in.

Check the render method of `Tooltip`.
    in Tooltip (created by NetworkIndicator)
    in div (created by NetworkIndicator)

Even though it's a warning, my component doesn't load and I get a white screen of death.
