Hello, We are having some compatibility problems caused by the lack of content-type in this part: https://github.com/openstack/swift/blob/5e5fde12400fc76b9df43b3fcd13eb8a2266... def GET(self, req): """ Handles GET Bucket versioning. """ sysmeta = req.get_container_info(self.app).get('sysmeta', {}) elem = Element('VersioningConfiguration') if sysmeta.get('versions-enabled'): SubElement(elem, 'Status').text = ( 'Enabled' if config_true_value(sysmeta['versions-enabled']) else 'Suspended') body = tostring(elem) return HTTPOk(body=body, content_type=None) Is there a reason for it?
