after new_droplet 'network' sometimes still empty

[kontrafiktion]

(using API V2):

when creating a new droplet I sometimes get the following error:

Traceback (most recent call last):
  File "create_droplets.py", line 20, in <module>
    create_droplet(a_group + '1')
  File "create_droplets.py", line 13, in create_droplet
    a_droplet = do.new_droplet( name, '512mb', 'ubuntu-14-04-x64', 'ams3', ssh_key_ids=['do-senacor'])
  File "/Users/vvolle/workspaces/net/dopy/dopy/manager.py", line 54, in new_droplet
    json = self.show_droplet(created_id)
  File "/Users/vvolle/workspaces/net/dopy/dopy/manager.py", line 75, in show_droplet
    json['droplet'][u'ip_address'] = json['droplet']['networks']['v4'][0]['ip_address']
IndexError: list index out of range

after creating the droplet, you seem to query the droplet immediately, but the networks might not yet have been set:
