Other addons ignore unknown URIs and mostly will return the index or root method. But the framework I'm using will raise an exception if something is unknown to me to avoid possible errors. In this case URIs the addon don't know and for my understanding this behavior is not documented.
I have to catch up some sleep. Tomorrow I test the skins and will come up with a solution

Ah, I see. Well thanks for looking into it for us.

FYI, thanks for this YouTube Addon. In combination with Super Favourites, I have several different links on my skin's homescreen linked to various YouTube channels and shortcuts through your addon. It makes things quite handy. And since the official YouTube addon seems never to work correctly when doing this, yours is a great, and even enhanced, alternative.

EDIT: Seems the latest version (YouTube (ALPHA 24) does fix my URI error issue in both Nebula and Confluence Custom Mod (CCM). Thanks.
