CachedFilesMixin breaks S3BotoStorage when used together because it applies "unquote" on the result of the storage url method.

There isn't really that much to add. The storage's url method result gets wrapped with unquote when using the CachedFilesMixin.
This sometimes produces a wrong url for the S3BotoStorage, since the Signature part in the url may contain %2B which is translated to '+' by unquote and then you get an authentication error from AWS when trying to remove it.

Calling unquote on the url seems like a side effect of the CachedFilesMixin that has no connection to what it's supposed to do so I think it should be removed.

This ticket looks valid. But the current patch isn't acceptable because it breaks tests (as mentioned by Karen on the pull request).

To move forward, the code should make it clearer which kind of path (filesystem, URL-unescaped, URL-escaped) in accepted and return by storage functions, and more tests must be added.
