Comment 1 Vytautas 2021-12-27 10:19:40 UTC

After further inspection, I've noticed that the cause of this is the search being interrupted by a change in the query. Like if you write the name of a theme, notice a typo and try to fix it, the system settings can crash.

Comment 2 Nate Graham 2022-01-12 01:27:56 UTC

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following that we need to figure out exactly what's going wrong:

> #6  0x00007f6729497c5a in Attica::BaseJob::doWork() () at /usr/lib/libKF5Attica.so.5

Could you please install debug symbols for Attica, 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!
