python-novaclient problem with PrettyTable 0.6

The 0.6 version of PrettyTable removed the "printt" function, causing a problem for python-novaclient. the solution appears to be to replace printt with "get_string" in utils.py, per a bugfix for openstack/python-keystoneclient:

Original question follows, with error message.

Hello,

nova client doesn't work on my Debian Wheezy.
Every command gives the same error:

ERROR: printt

Here is debug output for 'nova image-list' ('glance index' shows three testing images):

I can get list of images with 'curl X-Auth-Token' on http://192.168.0.1:8774/v2/tenant_id/images/detail
