Firefox 29, Win 7: On https://de.wikipedia.org/wiki/Ata_Demirer?debug=true#mediaviewer/Datei:Ata_Demirer_01.jpg on opening mediaviewer. Firebug shows: TypeError: mw.config.get(...)[this.namespace] is undefined https://bits.wikimedia.org/static-1.24wmf6/resources/src/mediawiki.api/mediawiki.api.js Line 222 (at "apiDeferred.resolve( result, jqXHR );") caused problem: not yet known.
This is caused by the image being used on a page with a non-standard namespace (itwiki has a custom namespace for wikiprojects apparently). mmv.ui.fileUsage creates new Title(pagename, ns) from the globalusage API, and then calling getUrl() on that fails.
