dbus @1.12.16_0: Startup items not started correctly

[rubendibattista (Ruben Di Battista)]

I'm experiencing problems with port that need dbus integration. For example if I run gimp:

2019-10-03 02:29:20.520 gimp[84942:5482481] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead.
Session D-Bus not running. Try running `launchctl load -w /Library/LaunchAgents/org.freedesktop.dbus-session.plist'.
Unable to read initialization file script-fu.init

(gimp:84942): GLib-GObject-WARNING **: 02:29:22.464: invalid cast from 'GtkMenuBar' to 'GtkWindow'

(gimp:84942): Gtk-CRITICAL **: 02:29:22.464: gtk_window_add_accel_group: assertion 'GTK_IS_WINDOW (window)' failed

So I checked the dbus processes running:

ps -A | grep dbus
84828 ??         0:00.01 /opt/local/bin/dbus-daemon --system --nofork

So the session daemon is not running.

So I do

sudo port load dbus

but still

ps -A | grep dbus
84828 ??         0:00.01 /opt/local/bin/dbus-daemon --system --nofork

If I then do:

launchctl start org.freedesktop.dbus-session

I get

ps -A | grep dbus
84828 ??         0:00.01 /opt/local/bin/dbus-daemon --system --nofork
85050 ??         0:00.01 /opt/local/bin/dbus-daemon --nofork --session

but still gimp (or Inkscape) don't get the connection to dbus.

MacOs version: 10.14.6 (18G95)

[jmroot (Joshua Root)]

Please show the output from sudo port -d unload dbus && sudo port -d load dbus.

[hugo-ribeiro (Hugo Ribeiro)]

I have the exact same problem. (Never reported it because gimp and inkscape still launch and are usable). Anyhow, I've attached the output of sudo port -d unload dbus && sudo port -d load dbus .

[hugo-ribeiro (Hugo Ribeiro)]

output from unload and load dbus with macports

[kencu (Ken)]

I have the exact same issue as well, and have never been able to figure out why dbus always delivers errors like this.

[rubendibattista (Ruben Di Battista)]

I can also confirm that the programs seem to work despite the error...

[rubendibattista (Ruben Di Battista)]

Other problematic port: evince. It does not work... Even if I launch manually the dbus session. (i.e. I cannot open any pdf).

@kencu @hugo-ribeiro can you try to open a PDF with evince?

[rubendibattista (Ruben Di Battista)]

Just wanted to ping here! The problem is still there...

[kencu (Ken)]

I see lots of dbus errors using evince on 10.6.8, but it does work to view documents

$ evince

(evince:76996): dbind-WARNING **: 09:00:40.404: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.a11y.Bus exited with status 1

of course, I see lots of dbus errors with every gnome program.

[kencu (Ken)]

I went through my HOME folder, and cleaned out several years worth of .XYZ directories, some of which seemed to be dbus related.

Since I did that, I'm no longer seeing these dbus errors!

Oh, could it be so easy....

[rubendibattista (Ruben Di Battista)]

The only dbus folder I had is .dbus-keyring. I removed it, but if I do the port load dbus I still get only the system session:

60388 ?? 0:00.02 /opt/local/bin/dbus-daemon --system --nofork

evince gives me error

Unable to open document “file:///Users/rubendibattista/git/x/Documents/presentations/output/presentation/main-presentation.pdf”.
File type PDF document is not supported

:(

And with inkscape I get the same ol' errors:

I loaded manually dbus-session:

launchctl start org.freedesktop.dbus-session

I seriously don't know what's wrong here.

[jmroot (Joshua Root)]

So it looks like base has loaded the launchd plists correctly. launchctl list | grep dbus should confirm that; run as your user to see dbus-session and as root to see dbus-system. The dbus-system job has KeepAlive set, so it will run all the time. The dbus-session job does not, since it runs per-user. It is meant to launch on demand when there is traffic on its socket.

I don't know what the problem is, but it seems unlikely to be at the launchd level.

[raimue (Rainer Müller)]

Make sure that the dbus environment variable is set in launchd in order to find the socket for the session daemon. If the following command returns nothing, something is not right.

$ launchctl getenv DBUS_LAUNCHD_SESSION_BUS_SOCKET
/private/tmp/com.apple.launchd.[...]/unix_domain_listener

If you are using iTerm2, the way it restores a previous session may break the setting of this environment variable through launchd. See the ​upstream report for details and workarounds.
