@shiverman See #1328

[phihag]

@shiverman You're not using the latest version ;) Type sudo youtube-dl -U to update to 2013.08.28 or newer.

[kevinisaac]

Version 2013.08.29 still shows the same error!

[mdmrcglu]

Hi kevinpaladin;
youtube-dl --update
Update to new version ( 2014.01.08...)

[phihag]

@kevinpaladin As @kale20 wrote, please update to a recent version. If the error persists, open a new issue with the entire output of youtube-dl when called with the --verbose option.
