After fixing the generation (the way patch #228401 does) in the Debian package, I still can't do "glance image-list":

# glance image-list
WARNING: The client is falling back to v1 because the accessing to v2 failed. This behavior will be removed in future versions
Invalid OpenStack Identity credentials.

And here's the corresponding output of glance-api.log and keystone.log:
