title: Title of Minimized Application in Ubuntu - Where does it come from?
body: <p>When an application is running in Ubuntu, it displays an icon in the top left corner and also a title - "Terminal" when terminal runs, "Files" when file manager. For my app it shows "Unknown". I want to change that.</p>
  
  <p>I inspected properties of the File Manager, and the word "Files" is not there. The name of the File Manager's Window is "Home".</p>
  
  <p>I inspected the org.gnome.Nautilus.desktop file and it does have a line "Name=Files". But similarly, my app has such line in its *.desktop file.</p>
  
  <p>Where does Ububtu (Gnome) takes the name which it displays in top left corner?</p>
