YouTube plugin does not play videos at all

[mspanc]

Totem successfully perform search but on double clicking the video tells that it cannot fetch the playlist.

In the console I have noticed:

As those errors differ from other ones mentioned in other bug reports about totem's youtube plugin, I open a new ticket.
