[trunk] KeyError: 'balance' when accessing the accounting dashboard

[Maxime Chambreuil (http://www.savoirfairelinux.com)]

Using server, web and addons from trunk without demo data, I installed the accounting module.

When I try to access the Accounting dashboard, I get:

Client Traceback (most recent call last):
  File "/home/max/openerp/web/trunk/addons/web/common/http.py", line 180, in dispatch
    response["result"] = method(controller, self, **self.params)
  File "/home/max/openerp/web/trunk/addons/web_graph/controllers/graph.py", line 77, in data_get
    'data': map(lambda record: _orientation(_convert(x, record[x]), record[yaxis[0]] or 0), res),
  File "/home/max/openerp/web/trunk/addons/web_graph/controllers/graph.py", line 77, in <lambda>
    'data': map(lambda record: _orientation(_convert(x, record[x]), record[yaxis[0]] or 0), res),
KeyError: 'balance'

I removed the graph causing this issue, but then I get another error message when accessing the dashboard:

Client Traceback (most recent call last):
  File "/home/max/openerp/web/trunk/addons/web/common/http.py", line 180, in dispatch
