Incorrect exception

Openerp 6.1

On create a sepa file, I get this error:

Traceback (most recent call last):
  File "/home/administrador/openerp/src/server/openerp/osv/osv.py", line 129, in wrapper
    return f(self, dbname, *args, **kwargs)

    except except_orm:
NameError: global name 'except_orm' is not defined

It's necessary either to add an 'from osv.orm import except_orm' or to change except_orm with orm.except_orm in line 298

thanks a lot.
