Yep, there's several:

$ ps ax| grep dbus
  1577 ?        Ss     0:00 /usr/bin/dbus-daemon --system
  4719 pts/2    S+     0:00 grep --colour=auto dbus
21453 ?        S      0:00 dbus-launch --autolaunch 
0147cf0965fedda7d4ee00360000000d --binary-syntax --close-stderr
21454 ?        Ss     0:00 /usr/bin/dbus-daemon --fork --print-pid 5 
--print-address 7 --session
21469 ?        S      0:00 /usr/bin/dbus-launch --sh-syntax 
21470 ?        Ss     0:03 /usr/bin/dbus-daemon --fork --print-pid 5

Logout kills some of them, but not all. The processes owned by "sddm" 
are not killed, unless I stop the sddm service.

What I noticed is that on logout, kuiserver5 and kded5 are not killed. 
On each login, additional ones are spawned. I can kill kuiserver5 
manually, but kded5 is unkillable, unless I force a "killall -9 kded5".

There's other weird issues as well when the desktop gets into the broken 
state. Clicking on links for example takes ages to open them in the 
browser. For example, if I click a URL in, say, Thunderbird, 5 times, 
nothing happens. Then, about 50 seconds later, they all open at once and 
5 new tabs appear in the browser. This doesn't happen prior to the 
desktop glitching up.
