In: '''django/core/files/utils.py''' line 12, in the definition of class `class FileProxyMixin` used in
form fileds to handle file uploads, there is:


{{{
fileno = property(lambda self: self.file.fileno)
}}}

which proxies to self.file.fileno... *but* self.file has no fileno attribute, which
produces an error on the access try...
