Question mark in the keyboard layout window
Hello, I have been trying for the past couple of days to get a custom keyboard layout working with gnome-control-center in NixOS.
I have raised awareness about this over at NixOS here: https://github.com/NixOS/nixpkgs/pull/47764#issuecomment-521997293
And I tried to do my homework and investigate where the issue might be...
So I am trying to find out why the title of the following window displays as "?". I assume you might know why gnome-control-center acts this way and it might help us build a patch for allowing custom keyboard layouts in Gnome.
Note: the "esrodk" layout is my custom xkb keyboard layout and when previewed it displays with a question-mark as the window title.
Note2: Even though it is set as default keyboard layout it is not applied by gnome. So far i noticed it working in the tty terminal.
Any input is greatly appreciated. Thanks
