Bug 432261

Application: plasmashell (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.10-200.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (Thirty Three)

-- Information about the crash:
- What I was doing when the application crashed:
I was switching between global themes from system settings
If I remember right the system was restarted right before the theme change.

- Custom settings of the application:
The theme was applied (to Breeze Dark)
Fresh Fedora Server 33 install with KDE, KDE apps, Firefox. Only the Home partition encrypted with luks2 using standard partitions (every partition, selected in the Fedora installer) with ext4 (every partition except the efi partition).
The only thing that I did on the install before changing the theme was changing the default Firefox settings and browsing.


The debugger to generate the backtrace was installed after the crash.

After the crash I get a bit of graphic glitches, to be more specific in the system settings app. A bunch of colors changing from what it's supposed to black. IIRC it is and was only in the settings tab (where I can navigate through the "pages" for example to the 'Search', 'Icons' 'Cursors' 'KDE Wallet' and others), the pages (for example the 'Global Theme' page where my themes are listed, but happens on all of them) are fine. Restarting the System Settings app fixes that.
Everything else seems fine.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
