Comment 3 for bug 1177610

the test test_snapshot_create_get_list_delete goes in error when executed against the XML interface with:

_StringException: Traceback (most recent call last):
  File "/home/gfidente/Devel/github.com/tempest/tempest/api/volume/test_volumes_snapshots.py", line 60, in test_snapshot_create_get_list_delete
    snaps_data = [(f['id'], f['display_name']) for f in snaps_list]
TypeError: string indices must be integers, not str

where snaps_data comes from:
resp, snaps_list = self.snapshots_client.list_snapshots()
