There is no upload log entry under File:鼈甲 祭器.JPG - this is where the file was initially uploaded. However the file is listed under the user's upload log as "File:\u9f08\u7532\u3000\u796d\u5668.JPG" (File:鼈甲 祭器.JPG). Note the \u3000 aka IDEOGRAPHIC SPACE. Now, when entering this title with ideographic space into Special:Log as the target, MediaWiki normalized the title to File:鼈甲 祭器.JPG (normal space). As a result, it's impossible to find this log entry by page name.
Downstream bug: https://commons.wikimedia.org/wiki/User_talk:Rillke/Discuss/2015#VFC_error_at_File:.E9.BC.88.E7.94.B2_.E7.A5.AD.E5.99.A8.JPG
Which could be described as "API Log reports title with IDEOGRAPHIC SPACE, page was never moved from its version with IDEOGRAPHIC SPACE to a normalized version but imageinfo normalizes the title to use the normal space \u0020. As a result the script that uses the upload title from the logs as a key doesn't find the file in the result set.
