Hi,

I'm trying to generate an Excel export of my clients list. After selecting the fields and clicking on "Export", I get the following error :

Internal Server Error

{"message": "OpenERP WebClient Error", "code": 300, "data": {"debug": "Client Traceback (most recent call last):\n File \"/usr/lib/python2.6/site-packages/openerp-7.0_20130624_231051-py2.6.egg/openerp/addons/web/http.py\", line 285, in dispatch\n r = method(self, **self.params)\n File \"/usr/lib/python2.6/site-packages/openerp-7.0_20130624_231051-py2.6.egg/openerp/addons/web/controllers/main.py\", line 1627, in index\n cookies={'fileToken': int(token)})\n File \"/usr/lib/python2.6/site-packages/openerp-7.0_20130624_231051-py2.6.egg/openerp/addons/web/http.py\", line 332, in make_response\n response.set_cookie(k, v)\n File \"/usr/lib/python2.6/site-packages/Werkzeug-0.9.1-py2.6.egg/werkzeug/wrappers.py\", line 960, in set_cookie\n self.charset))\n File \"/usr/lib/python2.6/site-packages/Werkzeug-0.9.1-py2.6.egg/werkzeug/http.py\", line 905, in dump_cookie\n value = to_bytes(value, charset)\n File \"/usr/lib/python2.6/site-packages/Werkzeug-0.9.1-py2.6.egg/werkzeug/_compat.py\", line 106, in to_bytes\n raise TypeError('Expected bytes')\nTypeError: Expected bytes\n", "type": "client_exception"}}

I have no idea what this means, something about browser cookies ?

EDIT : Here's what the server log says :
