Original GitHub issue: https://github.com/netblue30/firejail/issues/5925

Description

VLC, when configured with sudo firecfg, disappears from GNOME Settings app when trying to set a default media or music player

Steps to Reproduce

Run sudo firecfg and leave its default configuration
Open GNOME Settings Default Apps panel
VLC is nowhere to be found when trying to set it as default

Expected behavior

Run sudo firecfg and leave its default configuration
Open GNOME Settings Default Apps panel
VLC should be listed together with other apps that also have a firejail configuration. E.g. Firefox

Additional context

If the .desktop file located in ~/.local/share/applications/ is deleted, VLC appears normally in GNOME Settings App

Environment

Fedora Linux 38
firejail version 0.9.72

Checklist

The issue is caused by firejail
I can reproduce the issue without custom modifications (e.g. globals.local).
The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
The profile (and redirect profile if exists) hasn't already been fixed upstream.
I have performed a short search for similar issues (to avoid opening a duplicate).
I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

Have you seen https://github.com/netblue30/firejail/discussions/5074 yet? Sounds like you might need to remove the --started-from-file part in the Exec= line. Can you post both vlc.desktop files here please? Would be interesting to see what firecfg did to it exactly.

There is a recent PR that implements firecfg.d so you can create persistent overrides for problems like this. It's still in draft mode and you would need to build firejail from git.

# converted by firecfg
[Desktop Entry]

[...]

Exec=vlc --started-from-file %U
TryExec=/usr/bin/vlc
Icon=vlc
Terminal=false
Type=Application
Categories=AudioVideo;Player;Recorder;

Removing --started-from-file does not seem to add it as an entry in GNOME Settings unfortunately

If needed, I'm editing this to put more of the .desktop file

Is this a firejail bug or a GNOME bug? I.e. if you copy the .desktop from use/share to your home, does it work?

There is a recent PR that implements https://github.com/netblue30/firejail/pull/5876 so you can create persistent overrides for problems like this.

I copied vlc.desktop from /usr/share/applications/ over to ~/.local/share/applications/
It results in the exact same outcome. Both files are exactly the same upon opening and comparing them

Sounds like a GNOME issue. Did you tried to logout and login again?

If this has nothing to do with firejail I guess I'll just delete the .desktop file for now. Do you know how I can open an issue to the GNOME team regarding this?

The issue tracker for the GNOME settings UI can be found at https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues. However AFAIK GNOME recommends that you open issues downstream (https://bugzilla.redhat.com/bugzilla/) if you installed it from there.
