On my local wiki, when a page patroller reviews a new page and clicks the trash icon in the page curation toolbar nothing happens and the browser console shows
ReferenceError: wgCanonicalNamespace is not defined http://localhost/wiki/extensions/PageTriage/modules/ext.pageTriage.views.toolbar/ext.pageTriage.delete.js Line 160
The error occurs because I set $wgLegacyJavaScriptGlobals = false and the extension accesses global variables instead of using mw.config.get( 'wgCanonicalNamespace' ). Some day we'll disable this legacy misfeature on WMF wikis...
