AWS - EC2 console AMI registration fails

I cannot register my S3 BastionLinux AMI because I do not get the opportunity to specify the correct URL and the flash applet barfs on receipt of the 302 redirect from aws when I select my manifest path.  The domain is hard-coded and I thus cannot do anything about it:

http://s3.amazonaws.com:80/BastionLinux/ami-bastionlinux10-test01.manifest.xml throws a 302 to http://BastionLinux.s3.amazonaws.com:80/ami-bastionlinux10-test01.manifest.xml from which the javascript doesn't follow ..
