Comment 3 for bug 160804

It's actually rather common. In my settings submenu, There's a couple of options for configuring Java, even though I rarely run Java-based applications or go to websites with Java applets. There are people who have both Compiz Fusion and another window manager (e.g., Metacity), but both settings entries are in the settings menu.

Here's a use case for you:
Bob has noticed that Awn 0.2 has crashed when his Pidgin file transfer has ended. Knowing that the bug triagers will ask him various questions about his Awn configuration (as he has reported bugs for Awn before), he opens awn-manager from the desktop menu and copies down any configuration info that he feels is relevant to his bug, and submits his bug report with that information included.
