SUMMARY I own a Wacom One M, I noticed that chainging the display orientation setting causes a crash 100% of the time. STEPS TO REPRODUCE 1. Go to input > drawing tablet; 2. Go to display change screen orientation. 3. Go back to input > drawing tablet; OBSERVED RESULT Well on the flipside the tablet automatically changes orientation according to the display orientation, so in theory I didn't had to visit the setting module in a first place(and the option to change orientation is grayed out anyway). The system settings app crashed. EXPECTED RESULT It doesn't crash.

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #4 0x00007f48d8646d94 in ?? () from /usr/lib/qt/plugins/plasma/kcms/systemsettings/kcm_tablet.so > #5 0x00007f48d8647583 in ?? () from /usr/lib/qt/plugins/plasma/kcms/systemsettings/kcm_tablet.so Could you please install debug symbols for plasma-desktop, 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!
This also only happens without kcm-wacomtablet on wayland; Tried this out on my other device with x.org with both kcm-wacomtablet and xf86-input-wacom package; I will install debuginfod in a sec and replicate

Turns out I had debuginfod and the package also adds relevant /etc/profile.d entries + /etc/debuginfod.d files that get loaded into the env var
