Bug 489419

Application: plasmashell (6.1.1)
 (Compiled from sources)
Qt Version: 6.7.2
Frameworks Version: 6.3.0
Operating System: Linux 6.6.30-gentoo-x86_64 x86_64
Windowing System: Wayland
Distribution: "Gentoo Linux"
DrKonqi: 6.1.1 [CoredumpBackend]

-- Information about the crash:
I have a projector that, when turned on, generates disconnected and connected events. No event is generated when the projector is turned off.

Sometimes when I turn the projector on, plasma crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
