Description Gary Delp 2021-02-19 14:13:42 UTC
Application: systemsettings5 (5.18.4)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-65-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.2 LTS

-- Information about the crash:
On the indicated system, launching from the (Main -> Applications -> Preferences -> KDE System Settings) menu.
Crashes every time with the same backtrace.  I got as many dbgsym packages loaded for the backtrace as I could find.  Let me know if there are other symbol table packages that would improve the trace.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
