[Zope3-dev] securitypolicy bug

[Roger Ineichen]

Zope3 is running, but theres a small bug in 
src\zope\app\securitypolicy\zopepolicy.py", line 73, in checkPermission
    assert len(interaction.participations) == 1 # XXX
AttributeError: 'NoneType' object has no attribute 'participations'

If you start the server an connect with the browser, it popup's a 
login windows. In the background you see the ERROR Tracback.
It seems that we have at this time no interaction.
