OpenERP-web does not start: 'OpenERPSession' object has no attribute 'jsonp_requests'

Hi!

Here is what I get at startup since I last bzr-pulled openerp-web:

Traceback (most recent call last):
  File "/usr/share/pyshared/werkzeug/serving.py", line 153, in run_wsgi
    execute(app)
  File "/usr/share/pyshared/werkzeug/serving.py", line 140, in execute
    application_iter = app(environ, start_response)

    result = handler(environ, start_response)

    return self.dispatch(environ, start_response)

    return self.app(environ, start_response)

    self.gen.next()
  File "/home/fde/repository/openerp-web/addons/web/common/http.py", line 359, in session_context
    v.jsonp_requests.update(stored.jsonp_requests)
AttributeError: 'OpenERPSession' object has no attribute 'jsonp_requests'

I reverted to rev 1700 (chosen randomly) and it works fine. So my very clever guess would be that error was introduced somewhere between 1700 and 1763 :-)

Cheers!
