[CRASH] Skarner crashes at champ select (re produceable)

If the Skarner is selected and another sound is playing it will crash the client. If you pick him as time is running out it happens. If as you are picking him you select new summoner spells while his audio is playing it happens. I've only had this happen since I started using the battlecast alpha skarner. Not sure if that is part of the prob.
