Bug 488678

Application: yakuake (24.05.1)
 (Compiled from sources)
Qt Version: 6.7.1
Frameworks Version: 6.3.0
Operating System: Linux 6.9.5-gentoo x86_64
Windowing System: Wayland
Distribution: "Gentoo Linux"
DrKonqi: 6.0.90 [KCrashBackend]

-- Information about the crash:
Screen was locked. Laptop with external monitor and closed lid. External monitor wasn't turning off, was left on.
plasmashell was also crashed/unavailable, haven't restarted automatically. Crash report wasn't generated
Possibly another qt bug or fix haven't been backported from 6.8 to 6.7.1 (in gentoo)

The reporter is unsure if this crash is reproducible.

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