Description Rafael Lima 2021-04-20 16:46:25 UTC
Application: systemsettings5 (5.19.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-50-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed:

To reproduce this bug on my machine, just open System Settings. Then, if I click two options in the left menu, I get a crash.

In the backtrace reported here, I clicked "Global Theme" and then "Application Style", but the crash also happens with other options as well.

On my machine, this is reproducible 100% of the times.

- Unusual behavior I noticed:

This bug seems to be related to some recent updates on Kubuntu, but I can't tell exactly what package caused this bug. After the update, another weird thing happened: the user picture in the lock screen is square (insted of using a round overlay).

The login screen is normal and my picture appears round, but if I go to the Log Out screen, the picture is now square. Not sure if this has anything to do with the bug I'm reporting, but both things started happening together.

Running on Kubuntu 20.10 (KDE 5.19.5)
X11 / Nvidia GTX 1660

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
