Note that there isn't much I can do about #1, if in fact that is what happened to you. That is 'intended' behavior and if that is what occurred basically you just dropped in the wrong spot. :-)
#3 is definitely fixed, it won't crash now on that.
#2 is fixed from the viewpoint of restarting Docky, that item will no longer show. It will show until you restart it. I might fix the behavior so you won't have to restart it too but for now it is fine.
