ERROR: insecure string pickle

[CEOGavin]

I am trying to download -
https://egghead.io/lessons/javascript-redux-the-single-immutable-state-tree

But I get the following error -
[generic] javascript-redux-the-single-immutable-state-tree: Requesting header
WARNING: Falling back on generic information extractor.
[generic] javascript-redux-the-single-immutable-state-tree: Downloading webpage
[generic] javascript-redux-the-single-immutable-state-tree: Extracting information
[Wistia] k41wmxv1eg: Downloading JSON metadata
ERROR: insecure string pickle

Any idea what I may be missing?

PS - I have a paid account on EggHead.
