Comment 3 for bug 1993852

Confirmed on Kubuntu 22.04.1 in a GNOME Boxes VM. Booted ISO, selected "Polski" as language, clicked the "Install Kubuntu" button (which was now named something different), then pressed "A" on my keyboard.

When "A" is pressed, the two drop-down menus in the installer change to read "A user-defined custom Layout", and the following error message appears on the screen:

We're sorry; the installer crashed. Please file a new bug report using the command 'ubuntu-bug ubiquity' in a terminal. This will gather information about your system and your installation process. The details will be sent to our bug tracker and a developer will attend to the problem as soon as possible.
