Extension not working in Chrome 24

Question

I use the following lines to define BlobBuilder object and slice function in Chrome extension

    window.BlobBuilder = window.BlobBuilder || window.WebKitBlobBuilder;

Blob.prototype.slice = Blob.prototype.slice || function(start, length) {
    return this.webkitSlice(start, start + length);
}

It works in Chrome with version up to 23, but for the latest version 24, it does not recognize my definitions any more. For example, var builder = new BlobBuilder() will prompt an error: Uncaught TypeError: undefined is not a function .

Does anyone know what's going on here? Thanks!
