Client crash on DropItemEvent

Code:

  @EventHandler(priority = EventPriority.LOWEST, ignoreCancelled = false)
    public void onPlayerDropItem(PlayerDropItemEvent e) {
        e.getItemDrop().remove(); //Or e.setCancelled(true);
    }

If a creative player [not tested with survival] try to drag and drop a item from the inventory window, the game will crash [Console: End of Stream]. I don't see any chance to have something wrong with that code, is a bukkit issue?

Edit: Bukkit 1.2.5-R4.0
