        Oops, misfiled, I wanted to create this under jami-client-qt.

        I've rebuilt from scratch just in case, and I could still trigger a SEGSEV on account creation:

        Do you have webengine on guix? and https://review.jami.net/c/jami-client-qt/+/24253?

        Seems a duplicate of jami-client-qt#1037 (closed) as your libavutil is crashing with QMediaPlayer (I guess because of updating to ffmpeg 6). One solution can be to patch the wizard to add a static Image instead the MediaPlayer if no webengine for guix

        This is a build built from the jami source tree with: ./build.py --install --debug --distribution=guix ; it has webengine support, but still crashes.

        MMh in fact it seems to be a crash in avutil + webenginecore so different one.

        Is the same options used as our contrib (cause we don't have this on our packages at least).

        A work-around would still be to use the static image (or check if the MediaPlayer is working and use it if so). Also, in a conversation, is playing a video (like a webm) do the same crash?

        ./build.py --install --distribution=guix uses the Jami contribs (since it's for development purposes). It appears to crash not doing anything particular (just scrolling a conversation or two triggered it now).
