Guicorn does not choose stderr

Question

I have a Flask application with the following route:

@app.route('/')
def index():
    console = logging.StreamHandler()
    log = logging.getLogger("asdasd")
    log.addHandler(console)
    log.setLevel(logging.DEBUG)

    log.error("Something")
    print >> sys.stderr, "Another thing"
    return 'ok'

I run this with

python gunicorn --access-logfile /mnt/log/test.log --error-logfile /mnt/log/test.log --bind 0.0.0.0:8080 --workers 2 --worker-class gevent --log-level debug server:app

The logs are as follows:

2014-06-26 00:13:55 [21621] [INFO] Using worker: gevent
2014-06-26 00:13:55 [21626] [INFO] Booting worker with pid: 21626

2014-06-26 00:14:14 [21626] [DEBUG] Closing connection. 

What happens to my logs in the index method?

As with Gunicorn 19.0, gunicorn has stopped redirecting stderr to its logs.

Refer to https://github.com/benoitc/gunicorn/commit/41523188bc05fcbba840ba2e18ff67cd9df638e9
