Dear Maintainer,

Haruna crashes on startup since today after I upgraded from Qt 6.10 to
Qt 6.11:

haruna
unknown() : Native interface revision mismatch (requested 1 / available 2) for interface QWaylandApplication

KCrash: Application 'haruna' crashing... crashRecursionCounter = 2
KCrash: Application Name = haruna path = /usr/bin pid = 14401
KCrash: Arguments: /usr/bin/haruna
KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi
qt.nativeinterface: Native interface revision mismatch (requested 1 / available 2) for interface QWaylandApplication
kf.idletime.wayland: This plugin does not support polling idle time
fish: Job 1, 'haruna' has stopped

Haruna apparently has been rebuilt for the Qt transition.

The crash may still be related to the new Qt version.

Haruna does not crash when installed as a Flatpak.

Best,
Martin

I missed the still ongoing ffmpeg transition affecting Haruna:

https://release.debian.org/transitions/html/auto-ffmpeg.html

Should another binary upload fix the crash then I will close my bug report
of course.

mpvqt needs to be rebuilt against qt6-wayland 6.11.2 to fix this

A small correction. The change that caused this crash is in qt6-base.

Hitting the same crash here (Debian sid, libmpvqt3 1.2.0-3, haruna 1.8.1-1+b1,
Qt 6.11.2, Wayland session).

Here is a workaround:

    QT_QPA_PLATFORM=xcb haruna /path/to/video.mp4

Runs fine via XWayland, no crash. Cheaper than pulling in the Flatpak if you
just want haruna working while this is open.

As Rik pointed out mpvqt needs to be rebuilt against qt6-base. This
apparently has not happened yet. Haruna still crashes. mpvqt version here
is 1.2.0-3.

Could a rebuilt be triggered?

@Alban: Thanks for the work-around.

Best,
