Comment 5 for bug 219288

Sorry for late reply, I had some trouble with my mail. Anyway...

Thanks for quoting the README, it also lists the problematic area:

"The Name, Comment and Icon keys will be used in the interface."

Which is, the method itself of extracting the non-translatable .desktop files. These contain names and descriptions of the applications, exactly as they are shown in the menu. When packaging the applications, the template desktop.in files will be populated with translations of the names/descriptions, if available in the po file, then these packaged .desktop files will be extracted for use in app-install. The list of available applications is made from these .desktop files, so some names/description _may_ show up translated, but there is no guarantee for this. Also this process ignores translations made in Launchpad and packaged in the langpacks.

I'm attaching a screenshot with some untranslated strings, hope you see the problem.
