Hello, when building gtk-qt-engine , I see that resulting translations files are built: /opt/trinity/share/locale/bg/LC_MESSAGES/bg.mo /opt/trinity/share/locale/de/LC_MESSAGES/de.mo [...] But, is it normal that files are named like "language.mo" instead of "application.mo" ? For other applications, the translation file is always named like the application itself Ex: /opt/trinity/share/locale/de/LC_MESSAGES/filelight.mo I think there will be file conflict as soon as another application uses the same naming convention as gtk-qt-engine ...
