Compatibility with the new Blob()

[minj]

You are redefining window.URL.createObjectURL which causes it to fail when given a Blob object in browsers that support it

[minj]

I work around it by prepending this to the declaration:

var BlobBuilder = (typeof (Blob) == 'function') && (function() {
    "use strict";
    var FakeBlobBuilder = function() {
        this.data = [];
    };
    var FBB_proto = FakeBlobBuilder.prototype;
    FBB_proto.append = function(data) {
        this.data.push(data);
    };
    FBB_proto.getBlob = function(type) {
        if (!arguments.length) {
            type = null;
        }
        return new Blob(this.data, { type: type });
    };
    FBB_proto.toString = function() {
        return "[object BlobBuilder]";
    };
    return FakeBlobBuilder;
})()

Although, in all likeliness the whole polyfill should be rewritten according to Blob() api

I will get on updating BlobBuilder.js for the new API next week (or you can submit a pull request if you'd like to help). I'm very busy with finals this week.

Is there any updates in this problem?

It will be fixed this weekend for sure.
