I've got the same issue, just returned from the Temple of the Dead to give him his voice back and his armour is standing up in the 'T' position with his other gear lying on the floor. There is no character model to interact with at all.
It would be nice if someone could take the time to post the solution to this error, which is still present and un-patched since the original post 9 months ago.
