Comment 1 Nate Graham 2023-06-05 15:49:58 UTC

Cannot reproduce the issue with those steps and the backtrace is missing debug symbols and de-mangling that would help us investigate it. Can you follow the instructions at https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl *exactly* to get a better backtrace, and then paste it in here? Thanks!
