crash when lua["TableName'] return null several times

[GoogleCodeExporter]

What steps will reproduce the problem?
  LuaTable table=lua.GetTable("TablenName"); where "TableName" NOT EXISTS In Lua State.

when lua_getglobal(luastate,name) get nothing from luastate,"nil" will be at 
top of stack.if call "lua_getglobal(luastate,name)" many times,the stack will 
fill with nil and crash.

solution:
lua.cs:
public object this[string fullPath]
{
    get 
    {
        object returnValue=null;
        int oldTop=LuaDLL.lua_gettop(luaState);
        string[] path=fullPath.Split(new char[] { '.' });
        LuaDLL.lua_getglobal(luaState,path[0]);
        returnValue=translator.getObject(luaState,-1);
                if (returnValue == null) {

                    //说明: 如果没有获取到任何东西，需要清理一下堆栈，
                    //否则多次调用后，nil将把堆栈填满了
                    //if get nothing,we need pop nil,or the nil value
                    //will increase in stack.
                    //see:http://lua-users.org/lists/lua-l/2008-07/msg00099.html
                    LuaDLL.lua_pop(luaState, 1);
                    return null;
                }
        if(path.Length>1) 
        {
            string[] remainingPath=new string[path.Length-1];
                Array.Copy(path,1,remainingPath,0,path.Length-1);
                        returnValue=getObject(remainingPath);
        }
        LuaDLL.lua_settop(luaState,oldTop);
        return returnValue;
}

Maybe some place i dont know need fix too.
