Ran into the autolaunch problem the other day with somebody else and
debugged that issue.  It turned out to be a permissions problem with the
dbus launch helper.  dbus-daemon-launch-helper needed to have the
following permissions:

-rwsr-x--- 1 root dbus

where of course "dbus" should be the group that is set
in /etc/dbus-1/system.conf in the <user>xxxxx</user> setting.

can you confirm what permissions your dbus-daemon-launch-helper binary
has?  Mine is in /lib/dbus-1, but it's also been found
in /usr/lib/dbus-1 on other distros.
