Comment 3 for bug 821456

Yes of-course, I can answer those questions:

* Is this reproducible, does it happen every time?
Yes it is and it happens every time.

* If so, what specific steps should we take to recreate this bug?
First be sure that the youtube addon is enabled:
1. Open totem.
2. Edit > addons / extensions (I'm not sure the name in english) .

Once enabled:
1. Open the sidebar in totem.
2. Select the youtube explorer and search a video.
3. Double click to play any video.

Another way to reproduce the error:
1. Drag and Drop any youtube link from firefox to totem.

* Was this working before? If so, what changed between the time it was working and now, that it's failing?
Yes, it was working before, I think that youtube changed something since some firefox addons like "Easy youtube video downloader" and "FlashVideoReplacer" also got broken but were updated and now they work correctly.

Thank you!
