Hi all,
I have a very simple Flask application exposed to nginx thru uwsgi.
It works great up to Python 3.4, but with Python 3.5 I get this error:
ERROR:raccoon.thumbnailer:Exception on /adapt [GET]
io.UnsupportedOperation: fileno
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

return environ.get('wsgi.file_wrapper', FileWrapper)(file, buffer_size)
SystemError: <built-in function uwsgi_sendfile> returned a result with an

Is it a known problem or some kind of fault of mine?
Thanks in advance,
bye, lele.
