[Plone-Users] Plone 3.0 site borks at 'Invalid plugin id: credentials_basic_auth'

[Paul-Michael A. <plo...@ag...>]

Swayed by the sweet looks and promises of Plone 3.0, I attempted to  
create a site from Python 2.4.4, MacOSX 10.4, clean install of Zope  
2.10.4 and the released Plone 3.0 tarball.

The Zope installation was fine but when I added the Plone products  
and libraries and tried to instantiate a site, I got this error:

    Module Products.PluginRegistry.PluginRegistry, line 183, in  
deactivatePlugin
    KeyError: 'Invalid plugin id: credentials_basic_auth'
    Unhandled exception in thread started by <class

    AttributeError: adapters

Hmm. Hard to know what to look at first. Any ideas? I'm working from  
a fairly clean set of libraries (just replaced my MacBook 1 month  
ago) but I wonder if some zope eggs like zope.component or zope.event  
are wonky.

Ticket filed naturally <http://dev.plone.org/plone/ticket/

and ask the hive-mind for opinions.
