Hi everyone,from the stack trace by Gael and some experimenting myself I figured it is probably this qt6-multimedia upstream bug: https://bugreports.qt.io/browse/QTBUG-108221

Hello,
I can confirm the bug on my own Sid, after upgrading end of last week.
A quick GDB gives me the following stacktrace :

It seems something internal to Qt6Multimedia or PyQt, I wonder if one of
those packages don't need to be recompiled after some ABI change. But it
could be something else, I'm no expert in Qt.
