[BUG] I don't see the main window icon

[arteze]

Describe the bug
I can't see the main window icon, which should be a magnifying glass, instead I see a window icon.

To Reproduce
Steps to reproduce the behavior:

1. Open
2. See the icon

Expected behavior
I want the magnifying glass to appear.

What I want to know exactly is... What path are you trying to get the icon from.

Screenshots

Desktop (please complete the following information):

• OS: LxPupSc64 20.06
• I don't remember that well, I think it was with Pacman.
• 0.1
• localectl status
  It says unset, if you know how to set it better.

System Locale: LANG=C.UTF-8
    VC Keymap: (unset)     
   X11 Layout: (unset)     

Additional context

I recently had a problem with GTK3 and many icons changed, I don't remember if FSearch had any icon in the window, I think it did, it had the magnifying glass.

I would like to know how it works so I can get it to load the icon.
