JSXtransformer error for lowercase classes does not provide linenumber property.

[lolchocotaco]

When attempting to use a react class with a lowercase ClassName, the transformer is not able to display line on which the error occurred. It turns out that the event variable passed to the to function createSourceCodeErrorMessage(code, e) does not contain an attribute called lineNumber.

An error is thrown that states:
Uncaught TypeError: Cannot read property 'replace' of undefined

The actual error has only the properties stack and message.
Error: Lower case component names (myClass) are no longer supported in JSX: See http://fb.me/react-jsx-lower-cas at http://localhost:8080/app.js:undefined:undefined

I am running Yosemite and in Chrome. Also using the jsxtransformer and
react provided by the CDN.
