Public bug reported:


In IceHouse something has changed in Glance and when I try to launch an instance with option "create volume from image" it fails, because some attributes are absent in image dict returned from Glance. Different types of images were tried. RDO packages are used.

The image's onwer in the database was indeed NULL (and that should be
ok). If I add an owner to the image, then another attribute will also be
not found:

I have no idea why some image attributes are absent, but one of the
