Description jyotib652 2024-08-22 05:23:05 UTC

Application: plasmashell (6.1.4)

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.8.0-40-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 6.1
DrKonqi: 6.1.4 [CoredumpBackend]

-- Information about the crash:
Whenever I run my two docker containers on Docker-Desktop while two instances of VSCode(1 instance is runnng`npm run serve` and another one is running `go run ./cmd/api` through VSCode terminal) & Firefox/Google-Chrome browsers are already running in the background and then I try to click on the icons of Firefox/Chrome on the taskbar that's when Plasmashell crashes everytime without fail. So whenever I try to switch over the already running applications(firefox/chrome) by clicking on the icons displayed on the taskbar, the Plasmashell crashes and then for a brief moment the taskbar disapperas totally and then again the taskbar reappears.

The crash can be reproduced every time.

I think I have the same, for a month or something, I'm on KDE Neon as well.

For me I don't have the back traces available (they cannot be installed automatically and I don't know what to do, this page: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Preparing_your_KDE_packages:~:text=Neon%20has%20the%20debug%20symbols suggests that I should have them already), but I was looking at the live journal and it seems I have some pipewire related lines almost always before a crash:

```
sie 20 11:33:20 dzek-neon6 plasmashell[1928487]: kpipewire_logging: PipeWire remote error:  -2 unknown resource 4 op:4
sie 20 11:33:20 dzek-neon6 plasmashell[1928487]: kpipewire_logging: PipeWire remote error:  -2 unknown resource 4 op:7
sie 20 11:36:12 dzek-neon6 plasmashell[1928487]: kpipewire_logging: PipeWire remote error:  -2 unknown resource 4 op:4
sie 20 11:36:12 dzek-neon6 plasmashell[1928487]: kpipewire_logging: PipeWire remote error:  -2 unknown resource 4 op:7
sie 20 11:39:10 dzek-neon6 plasmashell[1928487]: KCrash: Application 'plasmashell' crashing... crashRecursionCounter = 2
```

on the other hand - they are usually 3 minutes apart and the crashes usually occur when I interact with the taskbar (switching windows).

Crashes are frequent if I frequently use the taskbar (up to once per 3 minutes even). I don't have Docker Desktop, I have the Docker deamon running, but it's not running any containers and the crashes are still here. I don't think Docker is related.

If you can guide me about the backtraces I can provide them as well.

Yes, I agree the Plasma-shell crashes has nothing to do with the Docker-Desktop or Docker. But I gathered all the debugging information from the Plasma-Shell Crash Handler this GUI Tool has a button to download the information and I did that. And through this tool I reported this bug along with the all debugging info.

It happens to me too. This since the update of KDE Neon from 6.1.3 to 6.1.4: simply if I click two consecutive times on an icon (i.e. google chrome) on the application task bar (on the bottom side of screen), plasmashell crashes. I've already sent all data through the crash handler window.
