It is a Qt bug actually, this commit fixed it:

$ git show e68a0da0b90
commit e68a0da0b907af7980481a3cf30f6b4b97c06b6e
Author: Alexander Volkov

Avoid crash when keysymToQtKey(keysym, Qt::ControlModifier) is called

For example when Ctrl+Home is sent by virtual keyboard on Wayland.

[systemsettings] [Bug 403580] Formats only offers invalid locales for German (en_DE)

KDE/Qt5 apparently uses the locale support in libicu. The list of locales
libicu supports is different from the locales glibc supports, there is
considerable overlap between the list of locales supported by libicu and glibc,
but the lists are not equal.

If the user chooses a locale in KDE which does not exist in glibc, it makes not
sense setting the LANG or LC_* variables to such a locale.

Yes, de_DE is also a valid locale for CLDR/libicu.  The list KDE
offers is very incomplete.
