[Health-dev] Tryton error in configuring wizard

[Blue Light]

Hello,
        I created the demo database by running the script health_demo_server.py.
After that I started the Tryton client and connected to the database. The first thing, I get a module configuration wizard in which I was asked to add users. I added user1 and then user2. When I tried to add another user, I got an error dialog. The following was the error.

Traceback (most recent call last):
  File "/trytond/protocols/jsonrpc.py", line 123, in _marshaled_dispatch
    response['result'] = dispatch_method(method, params)
  File "/trytond/protocols/jsonrpc.py", line 156, in _dispatch
    res = dispatch(*args)
  File "/trytond/protocols/dispatcher.py", line 154, in dispatch
    result = rpc.result(meth(*args, **kwargs))
  File "/trytond/wizard/wizard.py", line 252, in execute
    wizard = cls(session)
  File "/trytond/wizard/wizard.py", line 307, in __init__
    setattr(self, state_name, Target(**data[state_name]))
TypeError: ModelMeta object argument after ** must be a mapping, not int

It also said I could log a bug with Tryton. Is this a known issue?.  Should I file a bug with Tryton?.
Thanks
