That was how I understood it myself, Till.
Most of the *-notify utilities all seem to be renamed versions of each
other, duz they all seem to have the same, grab a cpu & kill it, bugs.
knotify4 running on mdv seems to get several copies started at boot time,
but I always had to go around with htop and kill the top listed one because
it was using 99% of a core. The rest seemed to be able to carry on w/o it
so I never tried to trace it down. But it appears there is only one copy
of dbus-notify running.
And I believe I have been quoting the wrong name, it is
"dbus-daemon --fork --print-id 6 --print-address 8 --session" that hung.
There is apparently one incarnation running per printer.
According to htop.
