Description Bruno Friedmann 2025-03-22 20:08:12 UTC

Application: gwenview (24.12.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.2
Frameworks Version: 6.12.0
Operating System: Linux 6.13.6-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.3.3 [KCrashBackend]

-- Information about the crash:
I use to have jpeg, raw (cr2,cr3,dng) and videos (mp4 h264 or h265) in the same folder.
Since the move to qt6, each time I use gwenview to read a picture, then a video, once you leave the video the crash occur.

Can be reproduced 100% of time.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault

The crash is in the phonon mpv backend, which is not developed by KDE. Please report this to https://github.com/OpenProgger/phonon-mpv
