Blueprint static content only works when response.direct_passthrough is False

[joaodlf]

I'm using the latest version of Flask (0.11.1) and the built in dev server, with the following Blueprint:

blueprint = Blueprint("admin", __name__, url_prefix="/admin", template_folder="templates", static_folder="static")
The template folder is working as expected, but any resources inside the static folder throw a RuntimeError: Attempted implicit sequence conversion but the response object is in direct passthrough mode.

After searching around for this error, I found the following discussion:
closeio/Flask-gzip#7

The solution used in that third party extension was to put in place the following code on app.after_request:
response.direct_passthrough = False

My static content loads fine with the above.

I was wondering if anyone has run into this issue with Blueprints and if there is a better workaround.

As I said on the SO question, I can't reproduce your issue. If this is a bug with Flask, you'll need to post an example demonstrating that. Please use SO for questions about using Flask.
