Now it's almost winter and three dwarves have died of thirst while standing in my main food pile, on top of a bunch of barrels, with Drink as their job. I was totally mystified until I noticed they put the "empty" barrels in that food pile. The barrels claim to contain "()", which has the description "This is a ." so I think they are the cause of my problems. Dwarves seem to stand on top of them and "Drink" but never get any less thirsty. Eventually they go to a different barrel and are fine.
I marked all the leather, crafts, drinks, and food on the trade negotiations screen the year before, so maybe they tried to bring me some stuff that doesn't exist? The humans normally bring a ton of food in barrels, but they only had the bugged barrels when I bought them.

They were then murdered by a bronze colossus, but then so was I, so it was okay in the end.
