Latest "Create Elastic Beanstalk Version" task is giving me grief with S3 regions

Just in the last bit, the "Create Elastic Beanstalk Version" task has started giving me grief when I try to create a new version with files stored in a bucket outside of the region of my application.

Start by reproducing the "Create Elastic Beanstalk Version" task with application files stored in an S3 bucket outside the application's region. Trace the task's handling of the Elastic Beanstalk version request and S3 location; done means a version can be created successfully across regions.
