Comment 1 Nate Graham 2023-03-06 23:38:11 UTC 
Thank you for the bug report! Unfortunately I can't reproduce the crash myself in Plasma 5.27.2, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #25 0x00007fe6815974cb in ?? () from /usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/kcms/systemsettings/kcm_fonts.so

Could you please install debug symbols for Plasma, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
