backtrace

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.
