Sharing a Soundcloud link

Uh, where is my post gone? Anyway, will try again : when I try to share a Soundcloud link in a new post (new song / activity, not on Soapbox), the link is replaced by... nothing. It kinda looks like a Tastebuds bug, trying to replace the url with the embed and failing at it. It's been like this for a while, so maybe it's time to fix this ;)
