[arch-general] Unable to contact D-Bus session bus [testing]

[Oon-Ee Ng]

Hi all, started having this problem a couple of days back with the
dbus-core removal move (and corresponding filesystem update).

http://pastebin.com/JKMN58jP is the result of journalctl -b

A whole bunch of my applications cannot contact dbus. Firefox is one,
even pulseaudio complains (though sound still works as it still runs,
go figure). gnucash cannot start, etc. etc., but those are just
symptoms. Oh, and ario and synapse are dumping core.

I downgraded immediately due to having some things to finish off. At
that time dbus was at 1.6.8-4, now its 1.6.8-5 (just updated again as
today I have a bit of time to debug).

Most likely cause I can see is (may be) the filesystem update. I have
gshadow, shadow, group, and passwd pacnew files, but no idea how to
merge them (should I swap the dbus IDs from the pacnew files in?). The
original files worked after a downgrade.

Thanks for your help & time.
