Hi!

I installed ceilometer in our lab environment. When I try to open the resource usage on dashboard, or do a list command with cli I've got the following error:

AttributeError: 'unicode' object has no attribute 'iteritems'

CLI debug output:

It's very strange that in the last response the API version seems to be v1.0 but it's deprecated and the requests go to V2 so I really don't understand what is going on.
