Can't add custom keyboard layout in System preferences I've created the custom keyboard layout using Ukelele and save an obtained bundle to /Library/Keyboard Layouts folder.

Unfortunately, when I try to add any new layout in System Preferences app (having something in "Keyboard Layouts" folder), it just crashes. Has anyone encountered this issue?

P.S. macOS 10.13.6
I have no problem installing and using your .bundle once the .icns file is removed.  I think there is something wrong with it.  

Here is a new .icns file which I think will fix the problem.  Let us know.
