Bug 476022

Application: dolphin (23.08.2)

Qt Version: 5.15.11
Frameworks Version: 5.111.0
Operating System: Linux 6.5.8-arch1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
Dolphin crashed while copying about 50GB to a usb drive. The window was closed, only the copy progress in the taskbar was visible. It reached about half progress when I left the PC and was already crashed when I got back hours later.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
