Cataclysm-dda: Error with crushing a hostile NPC with a car

[Trokinos]

Using recent build cataclysmdda-0.C-7821
on a world created with these mods :
"dda",
"no_npc_food",
"novitamins",
"boats",
"deoxymod",
"blazemod",
"Tanks",
"Mundane_Zombies",
"safeautodoc",
"StatsThroughSkills"
I also have the world NPC spawn rate set to 100 (so i can see sometime a random NPC as below that value i nearly never see any random NPC)

A hostile Random NPC murdered 2 friendly Random NPC that were travelling with my character.
I ran away and managed to reach my working car before the NPC figured out i should be next (as there was a zombie closer) .
Getting in the car and driving at high speed to avenge my fallen NPC friends, i rammed the hostile NPC.

It created a error , the last couple of minute of the log :
13:47:58.219 GAME : src/npctalk.cpp:2649: called calc_chance with invalid talk_trial value: 0
13:48:2.31 GAME : src/npctalk.cpp:2649: called calc_chance with invalid talk_trial value: 0

Such a dramatic story you have here.

As a side note, probably the message log could take NPC gender into account to describe it as her/him.

I do not know if it is related but i ran into another bug related with NPC and a vehicle.

DEBUG : map::unboard_vehicle: passenger not found

FUNCTION : void map::unboard_vehicle(const tripoint&)
FILE : src/map.cpp
LINE : 872

What happened is that a NPC turned hostile and fled from me, i followed him and he entered in a vehicle, moving a few tiles inside, i shot him there and the error happened when he died
