* this problem is solved by updating package python-glance_store from 0.1.8.2.1 to version 0.1.10-5.1 *

    Hi,

    I am currently running a openstack setup with a ceph backend for glance and cinder. 
    on icehouse it was working ok. I updated the setup to Juno and
    now I am not able to create volume from image anymore. The Volume status says error, However when I look at ceph with rbd there is a volume present.

    In the cinder volume log I can see ImageCopyFailure: Failed to copy image to volume: HTTPInternalServerError (HTTP 500)

update 2) at the glance api logs it says TypeError: 'ImageProxy' object is not callable

update 3)

A simple download from glance also does not seem to work, it fails with too many values to unpack

It looks to me it makes an sql query and the values returned cannot be parsed properly

    BR,
