Bug 370259 – media-gfx/gthumb-2.12.3: gthumb does not start when no /usr/libexec/gconfd-2 is running

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Martin Mokrejš 2011-06-06 11:22:33 UTC]

I have a server to which I connect remotely via ssh. For some reason, I cannot start gthumb:

$ gthumb 

** (gthumb:6320): WARNING **: GConf error:
  Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details -  1: Failed to get connection to session: Error connecting: Connection refused)

[cut]
(gthumb:6320): Unique-DBus-WARNING **: Unable to open a connection to the session bus: Failed to connect to socket /tmp/dbus-QlSvXA6iWs: Connection refused

(gthumb:6320): Unique-DBus-WARNING **: Unable to connect to the running instance, aborting.
$

It seems other machines have gconfd-2 running. After glancing over http://projects.gnome.org/gconf/ it seems the deamon is to be started by a session manager. Fine.

1. My local laptop running gconfd-2 runs xdm and fvwm2, and while I am logged locally throough xdm I can run gthumb. 
2. Another machine runs kdm and although no user is logged in I can start gthumb.

So, I had a look into /etc/conf.d/, etc/rc.conf and cannot figure out what is wrong on the server. Simplay, I just missing /etc/init.d/gconf. ;-)

Sounds like missing dbus-launch when running the session, resulting in a empty
or wrong variable of $DBUS_SESSION_BUS_ADDRESS

$ echo $DBUS_SESSION_BUS_ADDRESS

Bingo.

[Comment 3 Samuli Suominen (RETIRED) 2011-06-10 07:13:20 UTC]

So when you connect to the server remotely... What steps are you exactly taking, the commands? What gets executed? Because I'm not convinced this is a bug but just lack of proper launching of X.

[Comment 4 Martin Mokrejš 2011-06-10 11:04:43 UTC]

client $ ssh -X -Y server
Password:
server $ xterm &
server $ xv file.png # works
server $ gthumb file.png # doe not work

server $ ps -ef | grep dbus
adminrig 12892     1  0 12:59 pts/0    00:00:00 dbus-launch --autolaunch=2de8d29b404da6d8b1d95ff300053eef --binary-syntax --close-stderr
server $

No X-server is running there on a local console, but for what?

[Comment 5 Pacho Ramos 2011-06-19 11:35:11 UTC]

Maybe running "dbus-launch gthumb" could help

[Comment 6 Martin Mokrejš 2011-06-27 16:14:43 UTC]

I found some binaries were broken on the server. It seems the gcc -mavx flags the cause.

Jun 10 12:59:26 s00142 kernel: [89520.889592] dbus-daemon[12894] trap invalid opcode ip:7f3338d7c26b sp:7fff50a01820 error:0 in dbus-daemon[7f3338d5d000+66000]

I removing the offending CFLAGS item and recompiling some apps it started to work fine, and also recompile of dbus helped in this particular regard.

Sorry for the noise.
