Related to T364681: Issues with translatable pages on Wikidata due to revision id overflow... Probably...

Indeed. The call that fails is RevisionLookup::getRevisionByTitle($title, $revision), with the revision read from the revtag table. (To be exact, that call doesn’t throw, but it returns null, and the next line in TranslatablePage.php throws due to experiencing null.) It’s actually only used to display the diff between the current and the previously marked revision, but I’m not sure if simply suppressing the diff would solve the issue or only surface further problems coming from the unexpected revision number.

The database "corruption" on Wikidata was fixed manually, so this shouldn't be happening anymore
