I had mounted several partitions from a disk image a while back and apparently never unmounted them nor removed the partiton mappings. Got rid of those and now there's no "phantom" trash.
Now that you mention it, I've previously found that if you move items on a USB drive into the trash and then un-mount that USB drive before emptying the trash, the trash-full icon stays there until you either log out and log back in or re-mount that USB drive and empty the trash while it's mounted.
