This seems to be a regression, as I believe this was working with the beta. I don't have it pinned down entirely, but it seems to be related to an Annotation adapter I am using. The error occurs in zope.interface.interface, at the following location:
def providedBy(self, ob): ..... spec = providedBy(ob) return self in spec._implied Printing spec gives: <implementedBy zope.app.pagetemplate.simpleviewclass.SimpleViewClass from /usr/local/Zope-3.1.0c2/lib/python/zope/app/exception/browser/systemerror.pt> Also, dir(spec) includes '_implied', so I really don't know what's going on. It isn't likely to be important, but I have commented out the import of the C optimized version of this method, so I could attempt to debug it. The error changed when I did this (it was AttributeError: 'NoneType' object has no attribute isOrExtends), but I assume that was simply because the C code was cloaking the error. I've attempted to track this down myself, but I really had no luck. I think I'll do some trial and error editing of my Annotations adapter, and see if that effects it.
