Comment 1 for bug 1180836

mhh, I was going to work on this but there's something wrong with your report.

What version are you using? I checked master, grizzly and folsom and none of them have:

File "/usr/lib/python2.7/dist-packages/glance/registry/api/v1/images.py", line 447, in make_image_dict
    image_tags = image['tags']

And the line bellow is not on line N 117:

image_dicts = [make_image_dict(i) for i in images]

Did you modify that file?

Cheers
