Research direction

Start by reproducing the supplied playlist URL and trace the failure through YoutubePlaylistExtractor.java, YoutubeParsingHelper.java, and PlaylistInfo.java, using the reported stack trace as the entry point. Determine why this playlist is reported as nonexistent despite the issue's EU-specific title. Done means the playlist request no longer produces this reported failure, with a regression check for the URL.
