Nextcloud-client / Nextcloud-client-nautilus not working in Fedora 38 (Silverblue)

I had nextcloud-client nextcloud-client-nautilus layered in Fedora 37 Silverblue and upgraded to Fedora 38 Silverblue.

The system

$ rpm -q nextcloud-client 
nextcloud-client-3.7.4-1.fc38.x86_64
$ rpm -q nextcloud-client-nautilus 
nextcloud-client-nautilus-3.7.4-1.fc38.x86_64
$ rpm-ostree status

Using Qt 5.15.9, built against Qt 5.15.8

The issue

  • Nextcloud does not syncronize anymore.

  • I also do not see the icon / entry in Nautilus anymore:
    grafik

  • And if I start the Nextcloud client, it does not open the window as it did before:

    $ nextcloud          
    QSocketNotifier: Can only be used with threads started with QThread
    nextcloud.gui.application: Already running, exiting...
    $ nextcloud --quit # (this is what the desktop entry at /usr/share/applications/com.nextcloud.desktopclient.nextcloud.desktop does)
    QSocketNotifier: Can only be used with threads started with QThread
    nextcloud.gui.application: Already running, exiting...
    

    But no window is to be shown. So I cannot really access the Nextcloud client application window.

Ah simply restarting fixed the window issue at least:

$ killall nextcloud
$ nextcloud

So Nextcloud shows a window again and I know it is synchronizing.

However Nautilus integration is still not working.
