Hi everybody. I'm using the latest OpenErp version on Ubuntu 13.04 64-bit. I am able to use the modules correctly via browser, but at the same time I noticed a strange thing. When I open the terminal and type one of the

openerp-server {start|stop|restart|force-reload}

it returns this message

  Traceback (most recent call last):
  File "/usr/bin/openerp-server", line 5, in <module>
    openerp.cli.main()
  File "/usr/lib/pymodules/python2.7/openerp/cli/__init__.py", line 51, in main
    __import__(m)
  File "/usr/lib/pymodules/python2.7/openerp/modules/module.py", line 133, in load_module
    mod = imp.load_module('openerp.addons.' + module_part, f, path, descr)
  File "/usr/lib/pymodules/python2.7/openerp/addons/base_action_rule/__init__.py", line 23, in <module>

  File "/usr/lib/pymodules/python2.7/openerp/addons/base_action_rule/test_models.py", line 1, in <module>
    from osv import osv, fields
ImportError: No module named osv

However, the openerp-server, as said before, seems correctly loaded.

ps aux | grep openerp

Ideas?
