Public bug reported:

When you download this image with curl, you get a qcow2 file, NOT a gz file.
https://fedorapeople.org/groups/magnum/fedora-21-atomic-5.qcow2

When you use 
glance --os-image-api-version=1 image-create --copy-from https://fedorapeople.org/groups/magnum/fedora-21-atomic-5.qcow2  --container-format bare --disk-format qcow2 --property os_distro=fedora-atomic --property os_type=linux --min-disk 8 --min-ram 512 --name fedora-21-atomic-5 --is-public True


It will be stored as gz compressed file, and when you or nova downloads it will be gzip compressed as well.
glance image-download <id>  --file test.qcow2.gz


glance MUST not ask for gzip compression when it is unable to handle it.
glance SHOULD be able handle compressed content.

Note:
I had rbd backend.

I do not have this issue with the
https://download.fedoraproject.org/pub/fedora/linux/releases/23/Cloud/x86_64/Images
/Fedora-Cloud-Base-23-20151030.x86_64.qcow2  url, because the server
refuses to compress , regardless to what the client requests.
