[Bf-python] makeparent crash

[models at paposo.com]

makeParent() causes the autosave feature to crash blender on windows. Not sure why but someone else on elysiun called this too. I noticed it when trying to get the lattice routines working.  Here's my script:

import Blender
from Blender import Lattice
from Blender.Lattice import *
from Blender import Object
from Blender import Scene

myOb = Object.New('Lattice')
myLat = Lattice.New()
myLat.setPartitions(5,5,5)
myLat.setLatKeyTypes(LINEAR, CARDINAL, BSPLINE)
myLat.setMode(OUTSIDE)

myOb.link(myLat)
myCube = Object.Get('Cube')
myOb.makeParent([myCube])

sc = Scene.getCurrent()
sc.link(myOb)

Blender.Redraw()
...
The after a period of time blender crashes.
Heres' the stack trace:

static void split_libdata(ListBase *lb, Main *first)
{
 ListBase *lbn;
 ID *id, *idnext;
 Main *mainvar;
 
 id= lb->first;
 while(id) {
  idnext= id->next;  <------------------- crash accessing NULL pointer

I'll see if I can figure out what's going on.
