On investigation doing a git bisect, the crash is introduced in the following
commit:
https://invent.kde.org/plasma/discover/-/commit/0f4e5e2367d78105fe0241e76d316853e0b278e2
Further investigation narrowed this down to the addition of 'featuredAction'
line. Commenting this out (leaving the others) prevents the crash.
