Uploading to a EU bucket fails using the new version of S3 plugin (v0.4) with the error:

It seems that this happen when you access the wrong amazon endpoint.
I've solved it temporarily for our setup by doing a: client.setEndpoint("s3-eu-west-1.amazonaws.com"); both places where AmazonS3Client is initialized in the S3 plugin (we only have EU buckets). There probably exist some easy way of querying for the correct endpoint for a more general solution.
