I'm reading the code of ApiQueryDuplicateFiles and I think I've found the problem 18:07:17 - marktraceur: Base: The server does hash checks on files and should return a warning if there are two exactly similar files 18:08:16 - Vulpix: marktraceur: in this case, the file on commons was upload by a bot after it was uploaded to ukwikipedia 18:09:02 - Vulpix: He probably wants to bot-delete those kind of files from ukwikipedia so the commons version is used instead 18:10:03 - marktraceur: Base: So look at the contribs page for the bot? 18:10:37 - Base: marktraceur: which bot? 18:11:25 - Vulpix: This seems to be the problematic line: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob;f=includes/api/ApiQueryDuplicateFiles.php;hb=HEAD#l121 18:12:46 - Base: can you fix it? 18:13:34 - Vulpix: No, sorry, I have no mediawiki installation with a commons repository to check it 18:13:46 - Vulpix: File a bug on https://bugzilla.wikimedia.org/ end of blockquote
Sounds like the problem, which is fixed with Gerrit change #20519, which is part of 1.20wmf11 and that is not live right now.
