   Thanks for the response @Kami . I don't have access to that GCE environment anymore so I can't test, but I compared the August libcloud code to the current code and it doesn't seem like there were any changes to `libcloud/compute/drivers/gce.py` that would have fixed this issue:
   
   https://github.com/apache/libcloud/compare/5cbd788...4107267
   
   Hopefully the example object I provided above might shed some light into how GCP can return objects that have regions (but not zones) populated.
   
   Also, here is some code that I came up with to work around the issue, perhaps this may help in developing a proper fix:
   
   ```
   def list_all_instancegroups(gcp, projectid):
       instance_groups = []
       resp = gcp.connection.request('/aggregated/instanceGroups').object
       if 'items' in resp:
           for v in resp['items'].values():
               for ig in v.get('instanceGroups', []):
                   if 'zone' in ig:
                       try: instance_groups.append(gcp._to_instancegroup(ig))
                       except:
                           e = sys.exc_info()
                           print('{}: instancegroup: {}'.format(
                                projectid, e[1].value['message']), file=sys.stderr)
                           if e[0] != libcloud.common.google.ResourceNotFoundError:
                               raise
       return instance_groups
   ```
