I get this on my desktop but not my laptop, yet I have been unable to
find the difference that accounts for it. In the end I gave up and made
/usr/libexec/dbus-daemon-launch-helper world-executable :(
Thanks, that fixed it. It looks as if a process switches its UID to a
non-root UID.
Perhaps the ebuild should be fixed to install sys-apps/dbus with these
permissions.
Making it world executable is same as giving root to every user on your
system -- as it makes it possible to escalate to user 'root' or at least
group 'messagebus'
So... Instead, the problem is often solved by simple re-emerge:
# emerge -1 glib dbus dbus-glib
Often caused by glib's upgrade (or downgrade) or dbus's upgrade (or
downgrade) where dbus-glib hasn't been rebuilt with it
