Causes for this bug (summarized by Tim Starling):

  • extension-list was modified in git, but change was not properly deployed
  • WikibaseDataModel returns null from file level of its extension setup file, causing mergeMessageFileList.php to abort even when file was present
  • Bug in mw-update-l10n, see bug 50347
