[Grok-dev] grok vs PostmortemDebuggingHTTP: 0-1

[Wichert Akkerman]

After upgrading grok to 0.10 in my buildout I can no longer use the
PostmortemDebuggingHTTP server. A request to the Zope root drops me in
pdb:

zope.security.interfaces.Unauthorized:
(<grok.admin.view.Index object at 0x9d990cc>, '__call__', 'grok.ManageApplications')
> /local/buildout/eggs/grok-0.10-py2.4.egg/grok/publication.py(40)callObject()
-> checker.check(ob, '__call__')

Trying to continue results in a site error:

I find PostmortemDebuggingHTTP to be a great tool to help me poke at things
when they break, so this is a bit unfortunate.
