I think you need to do "appname = self.appname()" here. Or "appname =
appname(self)". But I tend to do it like this:
def __get_appname(self):
return self.mapping.get('appname', 'default string')
def __set_appname(self, v):
if not isinstance(v, str): # or unicode, whatever
v = float(v)
self.mapping['appname'] = v
appname = property(__get_appname, __set_appname)
(partly copied from another project, so I may have overlooked something)

The problem here is that this class implements your interface so due
to the zcml it has a security declaration for 'appname', but it does
not have a method 'appname' as you define it as an attribute, which
makes it not available on Zope startup. This can safely be ignored.
