[BlueBream] Error with tutorial

[Matt Whipple]

I'm new to Zope and am working through the tutorial in the documentation
(http://bluebream.muthukadan.net/doc/1.0/tutorial1.html).  After the
first part I'm receiving the following error after attempting to submit
a ticket.  Any guidance would be appreciated.  I realize this is a
pre-release platform and have no problems digging in the dirt if needed.

Module tc.collector.views:18 in createAndAdd         
>>  self.context[name] = collector
Unauthorized: (<zope.site.folder.Folder object at 0x924a4ac>,
