Hello, Thank you for the response. This is with a fresh install of OpenERP 6.0 RC1 web client with no modifications and with no customisations. i.e with demo data. As I again repeated earlier - the installation is on Ubuntu 10.04 LTS 64 bit. I tried connecting to the 64 bit server through an openerp 6.0 client installed on another 32 bit linux machine. The same error was repeated when tyring to print an accounting report. So may be it is a problem with the openerp 6.0 server running on the 64 bit LTS ubuntu? I am pasting the traceback here administrator@ubuntu:~/openerp-client-6.0.0-rc1/bin$ /home/administrator/openerp-client-6.0.0-rc1/bin/modules/gui/window/tree.py:140: GtkWarning: gtk_misc_set_alignment: assertion `GTK_IS_MISC (misc)' failed rb.set_icon_widget(hb) /home/administrator/openerp-client-6.0.0-rc1/bin/modules/gui/window/tree.py:145: GtkWarning: gtk_misc_set_alignment: assertion `GTK_IS_MISC (misc)' failed wid.insert(rb, -1) Traceback (most recent call last): File "/home/administrator/openerp-client-6.0.0-rc1/bin/widget/view/form_gtk/parser.py", line 121, in button_clicked model.get_button_action(self.form.screen, id, self.attrs) File "/home/administrator/openerp-client-6.0.0-rc1/bin/widget/model/record.py", line 375, in get_button_action obj._exec_action(result, {}, context=context) File "/home/administrator/openerp-client-6.0.0-rc1/bin/modules/action/main.py", line 171, in _exec_action self.exec_report(action['report_name'], datas, context) File "/home/administrator/openerp-client-6.0.0-rc1/bin/modules/action/main.py", line 58, in exec_report val = rpc.session.rpc_exec_auth('/report', 'report_get', report_id) File "/home/administrator/openerp-client-6.0.0-rc1/bin/rpc.py", line 185, in rpc_exec_auth return sock.exec_auth(method, *args) File "/home/administrator/openerp-client-6.0.0-rc1/bin/rpc.py", line 119, in exec_auth res = self.execute(method, self._uid, self._passwd, *args) File "/home/administrator/openerp-client-6.0.0-rc1/bin/rpc.py", line 136, in execute raise e tiny_socket.Myexception: ("warning -- Incorrect padding\n\n(, Error('Incorrect padding',), )", 'Traceback (most recent call last):\n File "/usr/local/lib/python2.6/dist-packages/openerp-server/netsvc.py", line 489, in dispatch\n result = ExportService.getService(service_name).dispatch(method, auth, params)\n File "/usr/local/lib/python2.6/dist-packages/openerp-server/service/web_services.py", line 685, in dispatch\n res = fn(db, uid, *params)\n File "/usr/local/lib/python2.6/dist-packages/openerp-server/service/web_services.py", line 763, in exp_report_get\n return self._check_report(report_id)\n File "/usr/local/lib/python2.6/dist-packages/openerp-server/service/web_services.py", line 741, in _check_report\n self.abortResponse(exc, exc.message, \'warning\', exc.traceback)\n File "/usr/local/lib/python2.6/dist-packages/openerp-server/netsvc.py", line 129, in abortResponse\n raise Exception("%s -- %s\\n\\n%s"%(origin, description, details))\nException: warning -- Incorrect padding\n\n(, Error(\'Incorrect padding\',), )\n') best regards, Arshad On Wed, Nov 3, 2010 at 1:34 PM, Fabien (Open ERP)
