Hello, DBus broke for me after last upgrade [0]. I'm using testing repository and have: dbus 1.4.20-1 dbus-core 1.4.20-2 dbus-glib 0.98-1 dbus-python 1.0.0-1

but disabling it and downgrading (via pacman -Syuu) to: dbus 1.4.16-1 dbus-core 1.4.16-1 dbus-glib 0.98-1 dbus-python 0.84.0-1

doesn't fix problem (not entirely at least). On testing Gnome starts in fallback mode, chromium and wicd-curses says: Failed to call method: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1

After downgrading, wicd-curses (which uses dbus-python) works fine, but other things are still broken.

dbus-daemon is present in process list... What can be wrong, where should I look?

[0] List of upgraded packages: http://pastebin.com/CYbTTaUQ Only: [2012-04-11 21:59] upgraded dbus-core (1.4.20-1 -> 1.4.20-2) looks suspicious to me, but downgrading only dbus-core to 1.4.20-1 doesn't change anything.

Cheers, Kacper Żuk

PS Sorry for my grammar...

Hello,

I had a problem with dbus shortly. The error messagtes were of the kind "file not found: /var/dbus/system_bus_socket" However, I use systemd (an init replacement using parallel and on-demand loading of system services) and have no idea whether this is somehow related. The issue is that the socket /var/run/dbus/system_bus_socket isn't created. On a systemd-System this task is done by the unit dbus.socket and my computer runs flawlessy after manually calling 'sudo systemctl restart dbus.socket'

I donÄt know whether this is of any value to you but who knows?

Good luck! Are you using [testing] ?

Could you please add the output of $pacman -Q systemd systemd-arch-units initscripts-systemd ?

Hello Alexandre, no, I'm not using [testing] but I have the same version of dbus and dbus-core like Kacper so I thought I'd post what I have. $pacman -Q systemd systemd-arch-units initscripts-systemd dbus dbus-core systemd 44-5 systemd-arch-units 20120410-1 initscripts-systemd 20120412-1 dbus 1.4.20-1 dbus-core 1.4.20-2 Regards!
