Description Patrick Silva 2020-05-10 16:01:28 UTC 
Application: plasmashell (5.18.80)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-45-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
I have 10 icons on desktop, they are arranged in rows and aligned to left.
Plasma almost always crashes when I drag any of the first 4 icons from left to right,
but Plasma doesn't crash when I drag any of the other icons.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 2 deadite66 2020-05-10 17:12:27 UTC 
i should add :

plasmashell 5.18.5
Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: 5.6.11-arch1-1 x86_64
Windowing system: x11
Distribution: Arch Linux
Comment 3 Patrick Silva 2020-05-10 18:00:35 UTC 
it's not Wayland specific. Plasma also crashes on X11.

New crash information added by DrKonqi

plasmashell (5.18.5) using Qt 5.14.2

Having the same issue here.

Dragging an icon on the desktop leads to a crash 100% of the time.

Additionally, plasmashell also crashes occasionally on login and even when manually restarting plasmashell.

I've tried resetting plasma settings, turning off compositing but the crash still occurs.


I have recently (10/05) updated plasma related packages to v5.70.0. Prior to this update, to my knowledge, I wasn't having these issues. The list of packages updated:

New crash information added by DrKonqi

plasmashell (5.18.5) using Qt 5.14.2

- What I was doing when the application crashed:

- Custom settings of the application:

Desktop breaks when you drag an icon on the desktop. And it happens all the time, but with some icons.

Stack trace with debugsymbols

Same problem in openSUSE Tumbleweed, as soon as I installed KF5 5.70.0 moving some icons (e.g. from Steam games installed via proton) cause Plasmashell to crash. Others meanwhile still work for some reason, but this really needs to be adressed. I attatched the full stack trace.
