OK.. let me add my 2 cents in here too. Plain old PvP can cost XP loss. It's a known bug.
I do wish you folks would read the orginal post as it is intended.

What part of that statement did you not understand?
I watched Undead being used last eve. For the most part players controlling Undead were mindful. If they died and lost control of the creature their team mates went after it, before it could do harm. HOWEVER, some find it funny to take an Undead to a lowbie area and turn it lose. "Won't those level 12 PC's be in for a surprise when they run into this beast." Or collect a couple of them and turn them lose inside a city gates.
I've already had a chat with a couple of players, after the fact. If an Undead is intentional release or the controlling PC dies in combat losing control of the Undead. Take SS to show you were attacked first. They are not like summons where they disappear on the control's death, rest, log-out. So if you dominate an Undead for PvP, relic defense or raiding be real careful. It's your butt on the line.
I would further suggest that the Undead be kept up in HoD, until the bugs get ironed out. It's your call, though.
As for setting traps that cause XP loss, widgets, exploding chairs.. take that up in another thread.
