Source code for NPC character creation - but how to call it properly?

[FCP]

The code (function):

csPtr<iCelEntity> CelTest::CreateNPCActor (const char* name,const char* /*factname*/, const csVector3& /*pos*/)
{
      csRef<iCelEntity> NPCzombie = pl->CreateEntity("zombie",bltest,"actor",
      "pcmesh","pclinearmovement",
      "pcnpcmove","pctimer",CEL_PROPCLASS_END);

   if (!NPCzombie) return 0;

   csRef<iPcMesh> zombieMesh = CEL_QUERY_PROPCLASS_ENT (NPCzombie, iPcMesh);
   zombieMesh->SetPath("/cel/data/");
   zombieMesh->SetMesh("test","cally.cal3d");
   if(!zombieMesh->GetMesh()) return 0;

   csRef<iPcLinearMovement> npclinmove = CEL_QUERY_PROPCLASS_ENT (NPCzombie,
        iPcLinearMovement);

   csRef<iPcTimer> zombieTimer = CEL_QUERY_PROPCLASS_ENT (NPCzombie,iPcTimer);
   zombieTimer->WakeUpFrame(1);

   return csPtr<iCelEntity> (NPCzombie);
}

Thats what I was able to pur together from documentation.... but when I call it some VERY bad things happen (unspecified flood of gibberish in the cmd window).

call code :
  //entity_dummy1 = CreateActor ("NPC", "", csVector3 (0,0,10));
  //if (!entity_dummy1) return false;

Any ideas why that happens?

upon closer inspection the"pile of gibberish" turned out to bea failed assertion on get_element function of the array.h in csutils ( in crystal space). No idea whythat happens though
