Would you be able to install the debug symbols for okularpart.so ?

See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports for some potential instructions

Comment 2 Albert Astals Cid 2022-09-30 14:36:38 UTC

Once you do that make it crash again (I understand you can make it crash all the time) and upload the backtrace again please.
