Support GNOME 3.26+ with no system tray

If I start Talk from Launcher it will close after a few seconds.

After removing @@u %U @@ Talk runs normally:

# cat /var/lib/flatpak/exports/share/applications/com.nextcloud.talk.desktop
[Desktop Entry]
Name=Nextcloud Talk
Comment=Official Desktop client for Nextcloud Talk
GenericName=Video and Chat Communication

I use Gnome3 on Debian Bookworm Back Ports.

After a few test Talk closes again after a few seconds.

If I run it with /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=electron-wrapper --file-forwarding com.nextcloud.talk it stays open.

Does the Gnome Launcher close Talk?

Edit: I mean running it in a console.

What is @@u %U @@ about?

[ggzengel]

I think it's Gnome3 Launcher.
But I can't find a logfile with more info.

I found this:

https://docs.flatpak.org/en/latest/flatpak-command-reference.html#flatpak-run

--file-forwarding

    If this option is specified, the remaining arguments are scanned, and all arguments that are enclosed between a pair of '@@' arguments are interpreted as file paths, exported in the document store, and passed to the command in the form of the resulting document path. Arguments between "@@u" and "@@" are considered URIs, and any "file:" URIs are exported. The exports are non-persistent and with read and write permissions for the application. 

and this:

https://specifications.freedesktop.org/desktop-entry-spec/latest/exec-variables.html

%U	A list of URLs. Each URL is passed as a separate argument to the executable program. Local files may either be passed as file: URLs or as file path.

Sounds like the app might be missing the appropriate background permissions in its manifest?

@ggzengel What version of xdg-desktop-portal are you using?

@ggzengel Could you, please, run the following and try again?

flatpak override --talk-name=org.kde.StatusNotifierItem com.nextcloud.talk
flatpak override --talk-name=org.freedesktop.StatusNotifier.Watcher com.nextcloud.talk
