Description jy6x2b32pie9 2024-05-28 17:13:14 UTC 
Application: plasmashell (6.0.90)
 (Compiled from sources)
Qt Version: 6.7.1
Frameworks Version: 6.2.0
Operating System: Linux 6.9.2-gentoo x86_64
Windowing System: Wayland
Distribution: "Gentoo Linux"
DrKonqi: 6.0.90 [KCrashBackend]

-- Information about the crash:
Laptop with 1. internal display disabled. 2. Lid closed. 3. External display connected.
External display was turned off, and laptop was left to lock itself.
~8 minutes after locking, external display was turned on and session was unlocked.
plasmashell briefly disappeared and appeared again after that.
Crash report was generated.

Automatic restart of plasmashell or drkonqi report doesn't happen if laptop goes to sleep (which happens after display is turned on, if sleep is enabled in power settings)

Duplicate of https://bugs.kde.org/show_bug.cgi?id=485313, but now with different, new-er version of plasmashell and more information.

Comment 14 jy6x2b32pie9 2025-03-14 16:32:32 UTC 
I can reproduce this at will and able to perform whatever procedures needed to find the cause, saw crashes with gdb attached. Have qtbase, qtdeclarative and plasmashell build with -Og -ggdb already...
Comment 15 jy6x2b32pie9 2025-04-15 20:32:47 UTC 
If I connect to laptop with crashing plasmashell over ssh and do `loginctl unlock-session` then plasmashell doesn't crash...
Comment 16 jy6x2b32pie9 2025-04-17 10:41:50 UTC 
Or not. Apparently, it decided not to crash only once, and resumed crashing afterwards.
Comment 17 jy6x2b32pie9 2025-04-25 05:09:17 UTC 
I think I isolated cause of the crash? If konversation is running, plasmashell crashes. If konversation is not running, plasmashell survives lock and unlock,

Hey, I can confirm that I use Konversation, so that's an interesting find!
Comment 19 TraceyC 2025-04-25 16:26:18 UTC 
I'm not able to reproduce this right now on git-master

Screen lock timeout - 1 min
Konversation running
1. Laptop closed with external monitor attached, disable laptop monitor in settings.
2. Turn off monitor.
3. Let KDE lock screen.
4. Turn monitor on (for me it turns on automatically when the laptop lid is opened)
5. Unlock KDE.

Leaving this for more experienced plasmashell contributors to look at
Comment 20 jy6x2b32pie9 2025-04-25 16:55:32 UTC 
Can you try:
Laptop. External monitor connected, Konversation is running, lid is closed. External keyboard is connected.
1. Lock screen with Meta-L (or your shortcut for screenlock)
2. Press Esc to blank and turn off monitor.
3. Wait a little.
4. Press any key to bring monitor back, to KDE lock screen.
There is double click of hardware disconnecting and connecting sounds.
5. Unlock.
6. Plasma crashes for me.

If you are on IRC I can send you a message while your desktop is locked. Perhaps the bug is triggered by Konversation presenting a notification while the screen is locked?

Comment 24 Akseli Lahtinen 2025-07-24 11:11:15 UTC 
I tried to repro this but had no luck.

What I tried was:

- set screen to turn off on locking
- open konversations and connect to network
- close it to tray
- lock screen and it turns off

Then on anothee device i send a query, but no crash.

I also tried to keep systemtray pinned open, so that it covers the area where the notification pops up. But didnt work either.

Well. Changed hardware. Now I can't replicate it myself.
Comment 27 TraceyC 2025-07-24 18:06:52 UTC 
Sentry has 270 events with 19 user reports, as recently as 3 days ago, so this is definitely still ongoing.

Different reported causes:
- System wake
- Connecting to TV over HDMI
- Connecting / reconnecting external monitor
- KDE Wallet
Comment 28 David Edmundson 2025-09-19 14:58:24 UTC 
Sentry implies this is fixed with Qt 6.9.2. Please open a new ticket if this crash occurs again
