Description Ethan D. 2024-03-12 12:50:52 UTC

Application: kpat (23.08.5)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.7.7-200.fc39.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 39 (KDE Plasma)"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I was playing Freecell with the hint assistant when he started to suggest to move a card then move it again to the same slot in loop. When I clicked on the "autoplay" button the app has crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KPatience (kpat), signal: Segmentation fault

Hi. I've had a quick go at duplicating this but am a little unclear how you triggered the problem.

Is it possible firstly fr you to try to duplicate it again to confirm if this is a reliable crash? If so can you please provide some detailed steps as to how you trigger this (especially how you engage the hint assistant) so I can try to duplicate it again?

Thanks
Nick

Hi.
I wasn't enable to reproduce this bug again. I engaged the hint assistant by clicking on the hint assistant button at every turn and after some turn (maybe about 50) the suggestion loop bug appended.
