master+frameworks having translations of catalog plasma_shell_org.kde.plasma.desktop also in catalog plasma-mediacenter does not make any sense, especially because the first catalog has a wrong name: ./shells/next/metadata.desktop:45:X-KDE-PluginInfo-Name=org.kde.plasma.mediacenter org.kde.plasma.mediacenter != org.kde.plasma.desktop
quoting from Scripty's log ( ftp://l10n.kde.org/141112.trunk_l10n-kf5 ): "ERROR: there are duplicated POT files: plasma_shell_org.kde.plasma.desktop.pot" The catalog plasma_shell_org.kde.plasma.desktop from plasma-mediacenter over writes the catalog plasma_shell_org.kde.plasma.desktop from workspace/plasma-desktop/, that is really weird
