Interesting... I don't even see user preferences, which have to do with thumbnails at all. If I were you would now ask for users who still have the problem and then I would give the user name to one of the Wikimedia guys, who have direct database access. They should give you the content of the rows, which are set in the table user_properties for this user. And then check, which one it is....
