Uploading without corrupting files - asp.net-mvc

Question

I am attempting to upload an image to my IIS 7 server, but it is coming out corrupted. The same code works on a local instance through Visual Studio.
Local headers:

Here is my upload method that is called by the upload form:
[HttpPost]
public ActionResult UploadPhoto(object qqfile)
{
// Get current logged in user
var currentUser = _staffRepository.StaffMembers.First(p => p.Login == User.Identity.Name.Replace("Domain\\", ""));
var length = Request.ContentLength;
var bytes = new byte[length];
Request.InputStream.Read(bytes, 0, length);
// bytes has byte content here. what do do next?
var fileName = currentUser.Login + ".jpg";
var saveToFileLoc = string.Format("{0}\\{1}",
Server.MapPath("~/App_Data/uploads"),
fileName);
// save the file.
var fileStream = new FileStream(saveToFileLoc, FileMode.Create, FileAccess.ReadWrite);
fileStream.Write(bytes, 0, length);
fileStream.Close();
return new RedirectResult("MyProfile");
}
If it is relevant I am using this File Uploader
The image comes out on the remote server as all NUL bytes. Any assistance is appreciated.

Turns out this was a Chrome bug that has since been fixed in stable 19.0.1084.52 (released 23rd May).
