Searches on YouTube giving Experiment Warning Message

I have it as well, but in Dutch: "Experiment: je zoekresultaten kunnen vertrouwelijke inhoud bevatten. Deel deze inhoud niet met mensen buiten Google."

Edit: looks like it might just be a botched revision.

Ah thanks for the info, was worried it was just me for a while although the YouTube discussion on Google Groups is pretty full of this now.

here is a screenshot of the same http://awesomescreenshot.com/048198m964
