This means that you do not follow the NBT format of mobspawner. 1.6.4 is not protected from incorrect data. Therefore, you must be careful. Perhaps you forgot to specify "RequiredPlayerRange", "SpavnPotentials.Type", or use int instead short
Monster spawner format: http://minecraft.gamepedia.com/Chunk_format#Tile_entity_format
I trying to make plugin that allows users to place their own mob spawners. Player tries to place spawner in the world, after plugin will detect needed spawner's configuration, spawn needed entity, tune it, place NBT container from entity to spawner, delete entity, tune spawner properties and that is all, spawner is ready. All works fine on localhost, but on remote server when I try to place spawner I lost connection with reason "Protocol error, unexpected packet".
Server: Bukkit 1.6.4-R2.0 Build #2918 Plugins: PowerNBT 0.7.3.1, My Own Plugin
It also tested on MCPC+ 1.6.4 and 1.5.2
P.S. Sorry for my bad english.
