The API Query: https://commons.wikimedia.org/wiki/Special:ApiSandbox#action=query&list=logevents&format=json&leprop=title%7Cuser%7Ctimestamp&letype=upload&leaction=upload%2Fupload&leuser=yurik&lelimit=10 says that Yurik uploaded https://commons.wikimedia.org/wiki/File:35px-Film_reel_and_film.jpg at some point, but both Yurik and https://commons.wikimedia.org/wiki/Special:Contributions/Yurik disagree. One of them is lying, and I guess it is the API.
https://commons.wikimedia.org/wiki/Special:Log/Yurik looks fine to me. You won't see it in his contributions since it's deleted. Check his deleted contribs if you have the appropriate permissions.
So he uploaded it and then forgot he uploaded it?
Guess so.
