Comment 1 Nate Graham 2022-02-04 16:48:46 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:

> #9  0x00007fba6c7dfbc1 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.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!

Hi Nate, thanks for the quick triage. Hope this has what's needed.

I'm learning through additional context online that this is probably ungraceful handling of bad behavior in NVidia's binary graphics driver.

Application: Plasma (plasmashell), signal: Segmentation fault
