Comment 6 for bug 143399

I tried to reproduce this error with Zope 2.7.6, Plone 2.0.5 and PloneCollectorNG where I have some workflow scripts with 'Manager'
as proxy role to send out notification email (required
when anonymous users file new issues). Unfortunately I could not
reproduce this behaviour with my setup.

So the first step to nail this down would be to write
a unittest that shows the described behaviour.
