Hello. When selecting Queues under Workplace in CRM 4.0 as user A, the "Invalid Argument" error message appears. The security role being used by this user A has read access to the Queues entity, so it does not appear to be a permission issue. Testing user A with the System Administrator Role displays the Queues, but copying the System Administrator role and creating a new role (without changing any settings under the System Administrator Copied role) also shows the "Invalid Argument" message under Queues with user A.
