I get this bug as well. The skeleton spawners spawn them every few seconds, and the room fills up with these unresponsive skeletons. I can hit them once, and they will flash red, but after that I can't interact with them. They will still push me around, however. After looking at the map with MCEdit, I'm not sure if the game even recognizes them as entities? They disappeared when I tried to remove the entities in that area with MCEdit, but they continued to spawn until I destroyed the spawner. They may have just disappeared because I exited the game though.
