Description jrschmersahl 2024-02-21 13:31:47 UTC

Application: dolphin (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-18-amd64 x86_64
Windowing System: Wayland
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I'm... Not entirely sure what happened, or whether I had Dolphin minimized or just behind other windows. But I do know that if I pull it back up while it's running but not being used, it will occasionally crash. This has happened a few times before, and I'm not sure why. There's very little consistency in when it happens as far as I can tell.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Comment 1 fanzhuyifan 2024-02-22 01:03:57 UTC

Thank you for your bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), as this version of the KDE software is out of support from KDE, and so it's possible that the bug exists only in Debian at this point.
Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding!

New crash information added by DrKonqi

dolphin (22.12.3) using Qt 5.15.8

Dolphin crashes when I do a drag and drop to another app (LocalSend) using touch screen. The bug seems to be reproducible.
Here is a record of the bug reproduction : https://www.mediafire.com/file/k295tnb5rn7xyb4/2024-04-06_18-45-23.mkv/file
And link to the software LocalSend i'm using : https://localsend.org/

In the hope it will be useful,
A new KDE Plasma user
