The bug might be that you're allowed to categorize the talisman to be pulverized since it's a quest item.
Quite possibly in which case I would ask why does OCD think it can be pulverized so that a data source can be corrected. That said, there are also problems with kbay auction items. I'll generate a list of specifics eventually but many of them are items I bought on kbay, wanted one for my DC and would like to sell the rest. Last time I tried OCD generated an empty message to kbay, IIRC.
