Subject: xdg-desktop-portal-gnome: Crashes in a wayland session

Date: Sat, 28 Jun 2025 20:58:52 +0200

Package: xdg-desktop-portal-gnome
Version: 48.0-2
Severity: important
X-Debbugs-Cc: paolo.redaelli@libero.it

Dear Maintainer,

xdg-desktop-portal-gnome crashes a Gnome session at login when selecting a wayland
session while it runs fine in an Xorg session.

Other wayland desktops such as enlightenment and wayfire run fine but
Gtk applications starts with a lag of dozens of seconds, showing in logs
a similar error. As far as I can say it is this, but I wasn't able to
find more details.

Please create a new user and log in as that user. If the bug doesn't
show there, then there is a problem with your user's config.

Thank you,

First of all, thank you very much for you prompt answer!

In a freshly created user the problem does not show so it is in my config.

I lauched "find ~ -iname "*xdg*"|less" and searched in dconf but I 
couldn't find anything relevant.

Where should I look? I'm a "lifelong" Linux user but this bug looks a 
little puzzling, otherwise I woulnd't have reported a bug ...

Thank you in advance for your attention...

Kind regards,

    Paolo

I don't know so here are a few other ideas:

Do you have any files in ~/.config/xdg-desktop-portal/ ?

Compare the output of  env  between the working and non-working users.

You could back up your config files, then remove files to bisect to
try to figure out what isn't working.

Thank you,

Do you have evidence of this crash? The Journal messages you quoted are 
about xdg-desktop-portal, and they indicate that xdg-desktop-portal-gtk 
(not xdg-desktop-portal-gnome) took too long to start up (which is bad, 
but is not a crash).

Please look at the systemd Journal with journalctl, preferably as a 
privileged user (root or a member of the adm group), to get an overview 
of what is happening at the time.

This is a message from xdg-desktop-portal, not from 
xdg-desktop-portal-gnome.

>Jun 28 13:45:09 acer-paolo xdg-desktop-por[3745]: Failed to create settings proxy: Errore nel chiamare StartServiceByName per org.freedesktop.impl.portal.desktop.gtk: È stato raggiunto il timeout

This is a message from xdg-desktop-portal about xdg-desktop-portal-gtk, 
and is unrelated to xdg-desktop-portal-gnome.

Same here.

>Jun 28 13:45:49 acer-paolo systemd[2105]: xdg-desktop-portal.service: start operation timed out. Terminating.

This is a message from systemd about xdg-desktop-portal, and again is 
unrelated to xdg-desktop-portal-gnome.

Actually I found  no evidence of a crash as either 
xdg-desktop-portal-gtk or xdg-desktop-portal-gnome exited with an error 
code.

I read the logs founding no apparent clue.

I somehow solved the issue removing ~/.config/dconf/user; I dumped its 
keys but again I couldn't find any potential issue.

Thank you everyone for your time and attention but my issue does not 
deserve to waste your time anymore, so I'm posting this to 
1108442-done@bugs.debian.org, signaling that it shall be closed.
