In fact, what /etc/init/plymouth-stop.conf shows that it's kdm's responsibility to kill plymouthd. If kdm hasn't done this, it's a bug in kdm. Reassigning to that package; the kubuntu folks should feel free to reassign this back to plymouth if they show that kdm is doing the right thing, but at the very least it'll be easier for the kdm maintainers to reproduce this issue than the plymouth maintainers, and there haven't been reports of this with gdm.
