Bug 473836

Application: yakuake (23.08.0)

Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.12-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
Whenever I open an application that uses Konsolepart (i.e. not Konsole itself, but Dolphin or Yakuake) it crashes on this line:

https://invent.kde.org/utilities/konsole/-/blob/25ad2a35a72ecb4e073786535f9bdf6cdc67fdf7/src/Screen.cpp#L2395

The crash can be reproduced every time.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
