Can't copy files larger than 100MB, folder to folder on S3

Hello
I have video files that I want to copy from folder to folder on Amazon S3. If the files are less than 100MB they copy just fine. If they are greater than 100MB they appear to copy but:

• The file size shows as greater than 1GB (when it is 100.4MB or so)
• If you download the file (video) and try to run it, it won't. But those less than 100MB download and run just fine
• If I copy paste the HTTP URL into browser I get something like this:
  AccessDeniedAccess DeniedC879716E1BBF10CFsB6gEIUi+QQOjwgBc/HRXK6GzZrz91We1qXePJ2dfomDPi6OaZCor2iWyL5Eat3e

As I said, any file less than 100MB copied from folder to folder works fine.
Thanks

This must be a bug in multipart copy feature which is used for files larger than 100MB.
