Comment 6 for bug 1594959

If it's been tested on Debian stable, the Mate version available is probably older (1.10 or 1.08 I guess) and from what I remember on Ubuntu, the issue didn't appear before Mate 1.12.

It would be worth checking on Mate 1.10 (or older) if the problematic .desktop files were fully translated or if they've been changed afterwards. I've listed them in my original beu greport: https://bugs.launchpad.net/ubuntu-mate/+bug/1592723
