Bug 482360

Application: neochat (23.08.5)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.7.8-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I'm afraid I cannot provide detailed info about this crash. I wasn't doing anything active with the window, just reading the group chat after sending a couple messages. Judging by the stacktrace, it could be caused by an event in another room.

The crash does not seem to be reproducible.

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