Error: "filename" when using youtube-dl embedded in a script

[GijsTimmers]

I'm using youtube-dl 2015.03.03.1 on Ubuntu 14.04. I want to use youtube-dl in an embedded way to extract the audio from YouTube videos.

Please consider the following script (test.py):

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys
from youtube_dl import YoutubeDL

def show_status(d):
    if d["status"] == "downloading":
        print "Downloading..."
        print d["filename"]
        sys.stdout.flush()
    else:
        print "Done:"
        print d["filename"]
        sys.stdout.flush()

ydl = YoutubeDL({"restrictfilenames": True, \
                 "ignoreerrors": True, \
                 "nooverwrites": True, \
                 "prefer_ffmpeg": True, \
                 "progress_hooks": [show_status], \
                 "quiet": True, \
                 "outtmpl": "%(upload_date)s_%(title)s.%(ext)s", \
                 "format": "bestaudio/best",
                 "postprocessors": [{
                     "key": "FFmpegExtractAudio",
                     "preferredcodec": "mp3"}]})

ydl.download(["BaW_jenozKc"])

Now run it:

[user@pc testytdl]$ python test.py

Done:
ERROR: 'filename'

After running it, the directory contains a new file, 20121002_youtube-dl_test_video.m4a.part, which is 315992 bytes in size. The desired mp3 file is not there.
