Comment 3 somin.jelinek 2025-11-30 23:58:11 UTC 
CORRECTION OF MY DESCRIPTION

Sorry for making so many mistakes, I'm doing this for the first time. In STEPS TO REPRODUCE, I forgot to add that this happens only when changing the theme with a checked checkbox "Desktop and window layout":

STEPS TO REPRODUCE
1. On Fedora 43 KDE Plasma go to System settings > Global themes
2. Change the theme to Breeze or Breeze Dark with a checked checkbox "Desktop and window layout"

ADDITIONAL INFORMATION
When the checkbox "Desktop and window layout" isn't checked, only the checkbox "Appearance settings" is checked, it doesn't happen and the theme changes without error.
Comment 4 TraceyC 2025-12-05 00:39:30 UTC 
Thanks for the bug report. As mentioned in the bug template, if something crashed, we need a backtrace. Please attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks!
