Comment 1 Nate Graham 2022-11-29 22:48:11 UTC

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

> #11 0x00007f3fb030d2d1 in  () at /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.so

Could you please install debug symbols for plasma-workspace, 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!

Comment 2 phd 2022-11-30 10:35:32 UTC

I wasn't able to reproduce it.
I will reopen this report if it happens again and submit a detailed backtrace.
