Just installed Nautilus on the Ubuntu MATE 19.10.
Navigated to /usr/share/applications
to launch some application by clicking on its icon.
When I click on the icon of the desktop-file for application this file is opened in text editor.
Moreover the icons are not shown:
How one can open application by clicking on its desktop-file in modern Nautilus?
I remember it was working as expected in Ubuntu 18.04 LTS.
