It has now been merged and is *different* than the original patch. If you pulled the earlier patch, please update to the final version. https://github.com/openstack/glance/commit/efd7e75b1f419a52c7103c7840e24af8e5deb29d 2) It was discovered that the patches submitted for stable/folsom and master (grizzly) did not completely solve the problem. The original patch only fixed the problem for the v1 API. The problem still existed for the v2 API.
