kdenlive-master-208-linux-64-gcc.AppImage or
/opt/kdenlive-22.04.0-1-x86_x64.AppImage crash when I try to start after "chmod
-x /usr/bin/pulseaudio". Sometimes it shows "Could not initialize preview"
before crashing, sometimes main window only briefly blinks.
I see in dmesg:

With /usr/bin/pulseaudio enabled it starts successfully from one user account
but crashes from another one (before even displaying a message about preview
pane being unavailable).
Typically the crash happens after second instance of the following console
messages:
ALSA lib
/home/appimage/Craft/BC/linux-64-gcc/build/libs/libasound2/work/alsa-lib-1.2.5.1/src/conf.c:4499:(snd_config_update_r)
Cannot access file /home/appimage/Craft/BC/linux-64-gcc/share/alsa/alsa.conf
(it crashes instead of outputting "no alsa devices available")
Workaround: explicitly and manually start PulseAudio for that user: `pulseaudio
--daemonize=false --exit-idle-time=-1 --disallow-exit=true`. Kdenlive then
starts properly.
