Description of your issue, suggested solution and other information

When trying to download a channel, youtube returns an HTTP 500 status for this particular video. All previous videos download with no errors. The error is reproducible. Debugging steps I've taken:

First, I tried downloading the video individually. As you can see, this worked perfectly fine:

I then tried sending a HEAD request to youtube with the URL I extracted from the initial run:

$ curl --head --location 'https://r4---sn-n0qqxoapo3-jaal.googlevideo.com/videoplayback?sparams=clen%2Cdur%2Cei%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cexpire&itag=251&ms=au&initcwndbps=2727500&mv=m&mt=1499992955&mn=sn-n0qqxoapo3-jaal&mm=31&keepalive=yes&clen=4172473&expire=1500014647&pl=22&mime=audio%2Fwebm&key=yt6&ei=1hNoWeOaPMe2ugWyz4LYDg&ipbits=0&lmt=1428230290972465&dur=215.881&source=youtube&id=o-AMclMaXWgwVvlSxQEYPlHmdGLY_Oj8CfcgqSMeNWoFC9&signature=0FC6E11C025D1206EB7D1D9B3A29269804107B2D.8A32880260A4F04535D361DFE453137F21049430&gir=yes&requiressl=yes&ip=<redacted>&ratebypass=yes'

Since this seemed normal, I tried dumping the video to console:

$ curl --location 'https://r4---sn-n0qqxoapo3-jaal.googlevideo.com/videoplayback?sparams=clen%2Cdur%2Cei%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cexpire&itag=251&ms=au&initcwndbps=2727500&mv=m&mt=1499992955&mn=sn-n0qqxoapo3-jaal&mm=31&keepalive=yes&clen=4172473&expire=1500014647&pl=22&mime=audio%2Fwebm&key=yt6&ei=1hNoWeOaPMe2ugWyz4LYDg&ipbits=0&lmt=1428230290972465&dur=215.881&source=youtube&id=o-AMclMaXWgwVvlSxQEYPlHmdGLY_Oj8CfcgqSMeNWoFC9&signature=0FC6E11C025D1206EB7D1D9B3A29269804107B2D.8A32880260A4F04535D361DFE453137F21049430&gir=yes&requiressl=yes&ip=<redacted>&ratebypass=yes'

However this produced no output. I increased the verbosity:

$ curl --location 'https://r4---sn-n0qqxoapo3-jaal.googlevideo.com/videoplayback?sparams=clen%2Cdur%2Cei%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cexpire&itag=251&ms=au&initcwndbps=2727500&mv=m&mt=1499992955&mn=sn-n0qqxoapo3-jaal&mm=31&keepalive=yes&clen=4172473&expire=1500014647&pl=22&mime=audio%2Fwebm&key=yt6&ei=1hNoWeOaPMe2ugWyz4LYDg&ipbits=0&lmt=1428230290972465&dur=215.881&source=youtube&id=o-AMclMaXWgwVvlSxQEYPlHmdGLY_Oj8CfcgqSMeNWoFC9&signature=0FC6E11C025D1206EB7D1D9B3A29269804107B2D.8A32880260A4F04535D361DFE453137F21049430&gir=yes&requiressl=yes&ip=<redacted>&ratebypass=yes' --verbose

As you can see, youtube responds with a 500. I am guessing that this is in response to a malformed request submitted by youtube-dl in some way, but not knowing the specifics of how the youtube system works I can only guess. I have replaced my real IP address with <redacted> throughout this bug report, including in URLs, for privacy reasons. I am more than happy to contribute any other information which may be of assistance. Thank you for your hard work on this great program.
