Comment 3 for bug 1576282

Applications written in QML using the ubuntu UI toolkit and the desktop/qt5 part should be covered: the desktop-launch script sets the APP_DIR environment variable to the value of $SNAP¹, and UbuntuI18n::setDomain(…) calls bindtextdomain() with $APP_DIR/share/locale².

However I’m not seeing this work. Testing with a snap of webbrowser-app, the compiled translations are correctly packaged under $SNAP/share/locale/[lang]/LC_MESSAGES/webbrowser-app.mo, however the UI appears untranslated.
