Could not pass InventoryClickEvent to Citizens

I've got a problem with my traders. I can open their Inventorys but I can't sell or buy Items. My Server is running on Craftbukkit 2098.
In the server.log file it looks so:

2012-03-20 15:59:09 [SEVERE] Could not pass event InventoryClickEvent to Citizens
