[Zope] Problems with roles in 2.7rc1 too?

Hello, Are there any known problems with roles and Zope 2.7rc1? I cannot get a Plone-workflow state to work properly, it denies access to all users - including the manager, even tough I've given the manager role all permissions. The only way to awoid the message appearing is to check the Acquire-box of the "Access contents information"-permission. This worked fine on Zope 2.6.2. Could anybody confirm that this is a bug, or am I doing something wrong? Thanks in advance, -Petter-
