>Description:
Mate (from wip) or XFCE4 - certain actions which need dbus hang at start when dbus is started (from rc.conf). This problem persists in 2014Q4 2015Q1 2015Q2 and stable but in my old laptop installation (2014Q2 + netbsd 6.1.3) everything worked well. I tried to fix it with my ip record in /etc/hosts which changed the behaviour bud did not fix it.

What happens is that parts of the desktop like panels start two minutes after desktop starts and terminal or caja/thunar have delays when launching, even terminal hangs, and it is not possible to launch a logout dialogue.

It can partly be solved by starting the desktops with ck-launch and without dbus running, but then some elements of the desktop like pulseaudio or power management refuse to work at all.

I think this is serious because it makes NetBSD as desktop fairly unusable, which is a shame considering that other parts of the system work very reliably.
>How-To-Repeat:
Install full NETBSD 6.1.5 amd distro.
Install stable pkgsrc (and wip for mate).
Compile mate or xfce.
add a line to your rc.conf:
"dbus=YES"
add a line to your .xinitrc:
"exec startxfce4 --with-ck-launch # starts XFCE"
or
"exec dbus-launch --exit-with-session mate-session #starts MATE"
(optionally add your hostname and ip to /etc/hosts)
run startx and you will see immediatelly
>Fix:
Partial fix:
insert a line in your rc.conf:
"dbus=NO"

I even tried to compile xfce or mate against older dbus (1.8.6) but the problem persists.
