YouTube - private playlist problem

[wiper2]

Hi,
I have problem with YouTube plugin with private playlist. Standalone video from playlist is working fine, but "Reverse Playlist, Play All, Shuffle.." doesn't work. When I chagne playlist status to public everything is ok.

I tried to delete .xbmc\userdata\addon_data\plugin.video.youtube\settings.xml with the same result.
