Image GET TypeError: 'ImageTarget' object does not support item assignment

How to get here:

Deploy devstack w/ ceph:

[glance_store]
rbd_store_pool = images
rbd_store_user = glance
rbd_store_ceph_conf = /etc/ceph/ceph.conf
stores = file, http, rbd
default_store = rbd
filesystem_store_datadir = /opt/stack/data/glance/images/

$ cinder create --image 7d007552-9b2c-4231-bff7-1fbabb4445ec 1
(cirros image from devstack)

$ nova boot --poll --flavor m1.nano --block-device-mapping vda=<id>:::0 vm1

$ nova stop vm1

$ nova image-create vm1 vm1-snap

$ cinder create --image vm1-snap --display-name vol2 3
  fails due to another issue in Cinder/Glance

$ cinder create --image vm1-snap --display-name vol2 3
  now fails w/ Glance HTTP 500

Looking at the ImageTarget class, the error is easily understandable: there is no __setitem__ method defined there. I wonder whether this is on purpose? If not, adding one should be easy :)
