I was just searching thru shopping List, scrolling down for what Im missing, etc... I suspect the icons (recent additonal) are the cause of the issue. It might not be needed due to repeat refresh as you scroll down.

20x C stack overflow [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ? [string "=[C]"]: ?

This isn't an auctionator bug - the error comes from changes that another addon, CanIMogIt, does to the shopping list view.
