Original GitHub issue: https://github.com/netblue30/firejail/issues/5474

Description

As I know both ibus and firejail have used ibus.portal to support IME for multi-language.
I make sure both ibus and firejail version is right.
After I tried firefox, chrome, input method work well.
But while I try gedit, after this error appears, gedit will exit:

Failed to register: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: org.freedesktop.DBus.Error.ServiceUnknown

Steps to Reproduce

No profile:

firejail --name=a --debug --allusers --env=GTK_IM_MODULE=ibus \
  --dbus-user=filter --dbus-user.talk=org.freedesktop.portal.IBus \
  --env=IBUS_USE_PORTAL=1 --noprofile gedit

With profile:

firejail --name=a --debug --allusers --env=GTK_IM_MODULE=ibus \
  --dbus-user=filter --dbus-user.talk=org.freedesktop.portal.IBus
  --env=IBUS_USE_PORTAL=1 - gedit

Expected behavior

gedit can be started and ime works well

Actual behavior

gedit will exit during starup

Behavior without a profile

firejail --name=a --debug --allusers --env=GTK_IM_MODULE=ibus \
  --dbus-user=filter --dbus-user.talk=org.freedesktop.portal.IBus
  --env=IBUS_USE_PORTAL=1 --noprofile gedit

Environment

Ubuntu 20.04
Firejail 0.9.64.5

Checklist

The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
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)

I can reproduce the issue without custom modifications (e.g. globals.local).

The cause of your problem: ^^, your modifications => this isn't an issue, maybe a support request but that should be asked in Discussions.

So gedit fails after it tried to register org.gnome.gedit. Guess what you have to allow.

org.gnome.gedit

which command argument should be used to bypass it?
