Prior to zope.interface 3.6.4, interface objects used the '__hash__' of the base 'object' type, which used the object's address as its hash: under Python3, objects which override '__eq__' are also required to override '__hash__'.
I would say that you need either to pin zope.interface to version 3.6.1, or else require a version of nevow which doesn't attempt to hash the interface object inside its '__new__' (if using the object as a dictionary key inside its own __new__ is truly necessary, then nevow should arrange to assign the '__name__' beforehand). -- You received this bug notification because you are a member of Divmod- dev, which is the registrant for nevow. https://bugs.launchpad.net/bugs/811792 Title: AttributeError: 'MetaTypedInterface' object has no attribute '__name__' Status in Divmod Nevow: Confirmed Status in Tahoe, the Lovely Accessible File System: New Status in zope.interface: Invalid Bug description: This is with Nevow 0.10.0 and zope.interface 3.6.4. David-Sarah Hopwood and Drew Perttula each independently reported this error. (I haven't seen it personally, I'm just reporting what they posted.)
