Make all gnome-session-properties AppStream strings translatable

[AsciiWolf]

The AppStream metadata were recently added for "Startup Applications" (gnome-session-properties) in Ubuntu 18.04; it would be nice if "The Startup Applications Preferences app allows configuring applications to run automatically when logging in to your desktop. This app complies with the FreeDesktop.org Desktop Application Autostart Specification so it will work even if your chosen desktop is not GNOME." string was translatable.

Still not fixed in latest Ubuntu release.

Thanks for your report!

What happened was that the AppStream metadata generator started to pull info from existing .desktop files for packages without explicit metainfo files. The gnome-startup-applications binary package is one of a myriad of such packages.

Since gnome-session-properties.desktop does not include a Description field, and as explained at the linked page, AppStream pulls that info from the package description, which is not translated.

So adding an AppStream metainfo file might help. However, the gnome-session source package is in main, and I'm not sure if the AppStream metadata generator has the ability to get translations from the /usr/share/locale-langpack directory. When looking at update manager, for instance, there is a gettext-data-not-found warning which indicates otherwise.
