The data is obsolete, can never be shown, and may even cause failing
ASSERTs in Ki18n, as i18n is used before QCoreApplication is initialized.
Side note: baloo_file and the other helpers (baloo_file_extractor,
baloo_filemetadata_temp_extractor from baloo-widgets) should be installed
in LIBEXECDIR, as these should never called by the user.
