S3 GetBucketLocation fails when location is US Classic

[tvh]

When the bucket's region is US Classic, Amazon S3 returns an empty string for the bucket's region:

<LocationConstraint xmlns="http://s3.amazonaws.com/doc/2006-03-01/"/>

This results in the following error in amazonka-s3:

SerializeError (SerializeError' {_serializeAbbrev = Abbrev "S3", _serializeStatus = Status {statusCode = 200, statusMessage = "OK"}, _serializeMessage = "empty node list, when expecting single node Region"})

This would also fail if LocationConstraint is set to EU.

Thanks for reporting, I'll look into fixing it.

Related to this, CreateBucket will fail to work in us-east-1 as well. According to http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUT.html, it expects the value to be missing in this case.

Right, thanks. It seems the decision to replace the stringly-typed BucketLocationConstraint from the service definitions with the core Region-type was incorrect, albeit convenient. I'll introduced a newtype for Region that can handle the expected de/serialisation behaviour.
