Python 2.7.7 on Windows returns Unicode from mimetypes.guess_type

[mcdonc]

This breaks static file serving under Pyramid, where it uses the guess_type API to determine the file type. See https://groups.google.com/forum/#!topic/pylons-devel/bq8XiKlGgv0 for more information.

It seems to me that this should be a webob bug with properly encoding the content_type property.

[mcdonc]

Yeah, it's not, however, because we use mimetypes.guess_type directly in FileResponse's __init__.

[mmerickel]

But it is being passed into the super constructor.

[mcdonc]

Yeah, I guess I was thinking about it totally sucking that the Paste http server silently cast Unicode to str in headers and then when you switched servers it would start to fail but I suppose we could change webob to do the casting, because it wouldn't have the same fails-sometimes-doesnt-fail-other-times behavior.

[mcdonc]

In any case, I think this commit is still fine, because it means we needn't make someone rely on the latest-greatest WebOb to get this workaround.

Please release an update on PyPI. We are totally broken when developing on Windows with Pyramid 1.5.1.

[mcdonc]

If I were you, I'd revert to Python 2.7.6 in the meantime, it's unclear when the next Pyramid release will be.

[mmerickel]

I'll investigate pushing a bugfix release in the next day or so.
