After reviewing the code and comments briefly, I think this is a bug. I am 
amazed that it has not surfaced before. I guess Invalid from zope.interface is 
simply not raised that often.

Feel free to fix the bug with a test. You can also release a new z3c.form 
version if you like. I can give you access
