Xubuntu 12.04: polkit-gnome-1-WARNING

[Guy]

In every started session I get this erros in .xsession-errors:

(polkit-gnome-authentication-agent-1:20860): GLib-CRITICAL **: g_variant_new_string: assertion `string != NULL' failed

(polkit-gnome-authentication-agent-1:20860): polkit-gnome-1-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

Expected: is to launch the session without those errors.

What happened: allways showing those errors.

More precisions:

I'm in autologin and autostartx with mingetty on tty1 without any display manager.

I would be glad if I could avoid seeing those errors everytime because I don't realy understand why dbus is looking for an org.gnome.SessionManager file without gnome installed.

I don't know if it has a relation with the problem but this is what I have in apport after every boot:

ERROR: apport (pid 13444) Thu May 17 07:32:58 2012: called for pid 1601, signal 11

Hi,

Thanks for your bug report.

The first warning is probably a bug in polkit-gnome-authentication-agent-1 itself.

"Dbus looking for an org.gnome.SessionManager file without gnome installed" (the second warning) is due to some features of gnome-session: polkit-gnome-authentication-agent-1 will try to register itself to gnome-session, which obviously fails with xfce4-session.

[Guy (guy-b)]

Thank you Lionel for your explanations, this is what I understood. Is there any way to avoid dbus of looking for gnome on a xfce4 system wich is quiet strange? And do I have to open an other bug report for the first error about polkit-gnome-authentication-agent-1 GLib-CRITICAL?

I forgot to mention that I'm usind xfce 4.10 but the errors were already present in xfce 4.8.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Guy (guy-b)]

Very glad to know it, because policykit - 1 -gnome errors is somethings that I'm experiencing seens version ubuntu 10.10 gnome 2 as far as can remenber... If you need more informations, wellcome.

[Gary M (garym)]

Seen also in Ubuntu Studio 12.04 (xfce 4.8).

[Guy (guy-b)]

After this morning updates:

libpolkit-agent-1-0 (0.104-1) to 0.104-1ubuntu1
libpolkit-backend-1-0 (0.104-1) to 0.104-1ubuntu1
libpolkit-gobject-1-0 (0.104-1) to 0.104-1ubuntu1
policykit-1 (0.104-1) to 0.104-1ubuntu1

Nothing better, still got the two errors:

(polkit-gnome-authentication-agent-1:31333): GLib-CRITICAL **: g_variant_new_string: assertion `string != NULL' failed

(polkit-gnome-authentication-agent-1:31333): polkit-gnome-1-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

[Guy (guy-b)]

I have tryied to change etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop to this (commented lignes):

[Desktop Entry]
Name=PolicyKit Authentication Agent
Comment=PolicyKit Authentication Agent
Exec=/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
Terminal=false
Type=Application
Categories=
NoDisplay=true
OnlyShowIn=XFCE
#;Unity;GNOME
X-GNOME-AutoRestart=true
#AutostartCondition=GNOME3 unless-session gnome
X-Ubuntu-Gettext-Domain=polkit-gnome-1

Without success, still thoes errors at every session.

Hi,
I also find this error line in the $HOME/.xsession-errors file in Lubuntu, today. This is Lubuntu Precise perfectly up to date.
You can see the 2 outputs of ~/.xsession-errors files here:
http://pastealacon.com/30431
http://pastealacon.com/30432

I hope all these ugly messages will be solved.

Regards,
Mélodie

Hi,

After the last policykit-1-gnome 0105-1ubuntu3.1, nothing better, still does errors in xsession.errors every time:

(polkit-gnome-authentication-agent-1:1369): GLib-CRITICAL **: g_variant_new_string: assertion `string != NULL' failed

(polkit-gnome-authentication-agent-1:1369): polkit-gnome-1-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

Seeing this in 12.10.

[James Stewart Miller (jamesstewartmiller)]

Also seeing this in 12.10. Having problems with pam authentication as gnome keyring daemon pid is not being exported to env at boot.

[James Stewart Miller (jamesstewartmiller)]

just reinstalled python-keyring which was updated recently and rebooted - environment variable is now set fine but I still have the .xsession-error as reported above.
Before I did this I was getting gcr-prompter asking for a login password to add to the keyring, starting at seemingly random intervals. I have not had this appearing since I restarted 10 minutes ago.

[James Stewart Miller (jamesstewartmiller)]

no - sods law - as soon as I posted the above comment, gcr prompter showed up and something has reset the gnome-keyring-daemon pid and the gnome keyring file in /run/user/user-name/ but has not changed the associated environment variables. It did this at the same time as I started the ubuntu software centre although that might not be related.
