List images through Openstack API returns HTTP 500

[Jeffrey Wilcox]

Using the following image:
 wget http://uec-images.ubuntu.com/lucid/current/lucid-server-uec-amd64.tar.gz
 uec-publish-tarball lucid-server-uec-amd64.tar.gz mybucket

I can list the images with the EC2 API with no trouble. But when I try the same thing with the Openstack API (using the openstack.compute wrapper library) it blows up. I traced through the openstack.compute API client, and it appears to be sending the right request per the OpenStack Compute DevGuide 3/1/11 (DRAFT) section 4.5.1.

 'http://192.168.200.50:8774/v1.0/images', 'GET', <<Authentication stuff>>
  or
 'http://192.168.200.50:8774/v1.1/images', 'GET', <<Authentication stuff>>
 (or the same with /images/detail).

I get back a HTTP 500 internal server error. In the nova-api log, I see that the cause of that is nova/api/openstack/views/images.py blowing up in the build function where it's trying to set "name": image_obj["name"].

Here's the stack trace:

Confirmed with python-novaclient:

$ nova image-list
'name' (HTTP 500)

[Brian Lamar (blamar)]

While I cannot reproduce with the latest glance, and returning an image without a name is unhelpful to the user (and in my mind a slightly large/more pressing issue) I realize that the API shouldn't 'blow up' when encountering an image without a name! :)

I should have a fix ready in a minute after checking to make sure other values aren't suffering from the assumption that they should...exist?

facing the same issue ...How to get the fix?

The only answer here is to upgrade to Diablo or Essex.
