Exception: AccessDenied when I click on "Indexes"

Hi,

I am testing your latest release and I fid this strange behaviour:
When I go to Administration->Configuration->Full text search->Indexes
I get a blank screen with this message in the server logs:

Exception in thread Thread-22:
Traceback (most recent call last):
  File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner
    self.run()
  File "/home/cache/dev/v5/server/bin/netsvc.py", line 455, in run
    result = self.dispatch(msg[0], msg[1], msg[2:])
  File "/home/cache/dev/v5/server/bin/netsvc.py", line 296, in dispatch
    raise Exception('AccessDenied')
Exception: AccessDenied

I go to netsvc.py, OpenERPDispatcher class, dispatch function:
it ooks like service_name 'koo' does not exist in GROUPS['web-services']

any ideas?

thnx
