Google+ Versus Picasa

I was having some trouble with Picasa earlier today. Perusing the help forums I discover that canceling your enrollment in Google+ will cause Picasa to forsake it's new social butterfly interface and revert to it's original, fairly straight forward interface, which I knew, understood and liked. Cool. So I do that and everything seems fine until I try and add a music video to a YouTube playlist this evening and then I get this.

which makes it sound like I would be going back to Google+. Gaaaaah! I wonder what's happened to my other playlists, not that it really matters, I hardly ever use them.
