Possible duplicate to my earlier report, but a different backtrace. https://bugs.kde.org/show_bug.cgi?id=448954
Comment 2 Stephane MANKOWSKI 2022-01-22 21:09:03 UTC 
Hi,
This call stack is strange.
The issue could be due to a bad alignment between  libraries.
Could you rebuild skrooge and test again ?

I can reproduce this after rebuilding. I tried out asan/ubsan but that showed nothing too.
