By Schmoozerd:

would be good to know which charge spells these are that cause problems, or on which npcs :(

A possible idea would be to add
if (obj == this) sLog.outError("Crahed with NPC %u", GetEntry());
before the ASSERT (or use a similar PrintError function for entry, but i didn't find this yet
