- What I was doing when the application crashed:
Sometimes drkonqi icon appears in system tray after restarting plasmashell process manually on Wayland
with 'plasmashell --replace'.

The crash can be reproduced sometimes.

New crash information added by DrKonqi

plasmashell (5.23.3) using Qt 5.15.3

- What I was doing when the application crashed:
kquitapp5 plasmashell && kstart5 plasmashell & using krunner

- Unusual behavior I noticed:
Normally notifications reappear after restarting plasmashell but this time they didn't. Rather DrKonqi appeared in system tray

New crash information added by DrKonqi

plasmashell (5.23.3) using Qt 5.15.2

- What I was doing when the application crashed:
- I had hibernated the machine
- I started it up again after a few hours and it came up normally to the screen lock password request.
  - I wrote the password which was accepted
  - then it showed for 1 second the situation as it was when I hibernated the machine, but 
  - then it went again to the initial black loading screen with the rotating gear
  - I sweared again because every time I start KDE from sleep or hibernate there's always some problem!
  - then I clicked on ctrl-alt-f1 and the black screen went away and all looked normal
- there was a problem though: a "kwin_wayland" taking 100% CPU (line from "top" below):
    28430 antonio   20   0 2482100 145980 113316 R 100.0   0.5   2:45.34 kwin_wayland          
- I tried to kill it, but it didn't die, and it is still running as I am writing this report!
- then I ran "plasma_shell --replace" and I got this SIGSEGV report

- Unusual behavior I noticed:
  - The the initial black loading screen with the rotating gear appeared just after unlocking the screen
  - it went away by pressing ctrl-alt-f1 (I don't know why!)
  - kwin_wayland was stuck on 100% CPU
  - tried to "plasma_shell --replace"

Still happening in plasmashell 5.24.4 (Fedora Rawhide).

Comment 6 Nate Graham 2022-01-16 15:20:31 UTC 
I'm able to reproduce this intermittently when restarting kwin_wayland. Usually plasma fails to start automatically (Bug 448475), but when it does start, it crashes with this backtrace.

Prevent double deletion of shmpools

They are tied to the lifetime of the tiles, so don't also make it
managed by qApp.

New crash information added by DrKonqi

plasmashell (5.24.4) using Qt 5.15.3

- What I was doing when the application crashed:

I restarted plasmashell using script i have bound to hotkey. Script:
kquitapp5 plasmashell || killall plasmashell && kstart5 plasmashell

- Unusual behavior I noticed:

Before the crash plasmashell was bugged after plugging in external monitor. Plasmashell restarted normally, but DrKonqi icon appeared.

- Custom settings of the application:

I have moved panel to left side of the screen and set it's width to 80 pixels.

Git commit 50eaece7aef004b588a684c9fadff0f6787f2ef8 by David Edmundson.
Committed on 15/07/2022 at 06:05.
Pushed by davidedmundson into branch 'master'.

Scope DialogShadows lifetime to application

- DialogShadows own KWayland::Client::buffer objects
 - Buffer cleanup makes wayland calls
 - wayland calls after QGuiApplication has stoped will fail

Q_GLOBAL_STATIC mangaged objects can outlive the QGuiApplication.
