Reimaging a volume from an image that is volume-snapshot backed fails.
Steps to reproduce:
1. Create a bootable volume from image
2. Launch an instance from the image
3. Snapshot the instance - this will create an image reference and a snapshot of bootable volume
4. Reimage the volume using the above snapshot image -- this fails with the following trace
