[Zope] problem with checkPermission or viewThreadsAtBottom?

[Marc Lindahl]

Is there something going on with checkPermission or viewThreadsAtBottom  
that changed from either zope 2.6.2 to 2.7.0 or from plone from 2.0RC5  
to 2.0RC6?

Someone sent me this error traceback.  The product works under zope  
2.6.2, cmf 1.4.2, plone 2.0rc5.

When I try to add a new CMFAudio object to 'My Folder', it returns the  
following error:
