linuxdeploy with qt and appimage plugins fail generating a fully working qtquick+qtwebengine appimage

[paoletto]

appdir.tar.gz
simplebrowser.tar.gz

Attached the simple webengine based qml application, and the appdir stub used for the packaging.
Before attempting, using

DEBUG=1 QMAKE=/local/local/builds/qt5/bin/release/qtbase/bin/qmake QML_SOURCES_PATH=/local/local/builds/SimpleBrowser ../linuxdeploy-x86_64.AppImage --appdir appdir --plugin qt --output appimage

i did copy the appdir.bak into appdir, then the binary into appdir/usr/bin/simplebrowser

/local/local/builds$ ./linuxdeploy-x86_64.AppImage --list-plugins
linuxdeploy version 1-alpha (git commit ID 1d3d974), GitHub actions build 115 built on 2022-09-13 13:23:50 UTC
Available plugins: 
appimage: /local/local/builds/linuxdeploy-plugin-appimage-x86_64.AppImage (type: output, API level: 0) 
qt: /local/local/builds/linuxdeploy-plugin-qt-x86_64.AppImage (type: input, API level: 0) 

On a separate note, windeployqt also deploys an additional binary, QWebEngineProcess.exe

The demo applications we test against seem to work fine currently. Can you please provide a build and runtime log to show your problem? Maybe we need to update one of the deployers.
