If file not found: "During handling of the above exception, another exception occurred: ..."

When I try to include a non-existing file from static directory via {{=url('static', 'img/portrait.jpg')}}

I get this exception:

> ERROR in wsgi [\weppy\wsgi.py:110]:
Application exception:
Traceback (most recent call last):
  File "\weppy\stream.py", line 50, in streamer
    stream = open(static_file, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: '\\static\\img/portrait.jpg'

During handling of the above exception, another exception occurred:

  File "\weppy\wsgi.py", line 94, in error_handler
    return static_handler(app, environ, start_response)
  File "\weppy\wsgi.py", line 83, in static_handler

d(s)

I think this is a bug because one exception triggers another one.

Yes, this probably caused by the change on standard IO exceptions since python 3.3 Will fix this asap.

[GiantCrocodile]

Now there is no exception thrown, if the file doesn't exist. Is this expected? I doubt it.

@GiantCrocodile Are you sure? You should have an empty response with status 404

[GiantCrocodile]

Yes, the page is loading but without the image (I only see alt-tag) and I see this in console:

[127.0.0.1 on /static/img/portrait.jpg] dispatched in 0.005000591278076172 second(s)

Edit: I see in network analyse tab of FireFox that the resource has status 404. Maybe we should print it in console too? In console it looks like it is successful dispatched which is not true.

@GiantCrocodile will probably enhance the response to have a body stating the error.
