Traceback auditrail OCB 6.1

  File "/opt/openerp/testing/nafsa/server/openerp/addons/base/ir/ir_attachment.py", line 40, in check
    cr.execute('SELECT DISTINCT res_model, res_id FROM ir_attachment WHERE id = ANY (%s)', (ids,))
  File "/opt/openerp/testing/nafsa/server/openerp/sql_db.py", line 152, in wrapper
    return f(self, *args, **kwargs)
  File "/opt/openerp/testing/nafsa/server/openerp/sql_db.py", line 212, in execute
    res = self._obj.execute(query, params)
ProgrammingError: can't adapt type 'dict'

Steps to reproduce:
1. install Auditrail module
2. Define one rule for model ir.attachment
3. Mark Action check box
4. Try to access any atachment on any object.
...

Note: If action check box is not activated, error do not happen.
Even if action check box is activated, it works for rules in other objects like Sale order or invoices. Traceback is only happening on case of model ir.attachment on rule.

I don't know if I need reporting this bug also in OpenERP official branches since it's happening on 6.1.
Pending on my side to test on 7.0 and trunk.
Thank you:
Ana
