Download an old version of SpecialInterwiki, before it was renamed[see below] 3. run installer 4. select extensions 'Interwiki' and SpecialInterwiki The SpecialInterwiki -> Interwiki rename happened 2010-04-17: https://git.wikimedia.org/commit/mediawiki%2Fextensions%2FInterwiki/3a46e6374ee5426e5dce60280e7c71522a4b31b5 the version before that is needed; Fedora Core's last packaged version of this extension is '0.11.20080913svn' Expected result: The installer detects there are two extensions with the same class (SpecialInterwiki), and notify the person running the installer. Actual results: The installer offers both, and (if selected) they crash the installer.
