Ubuntu mint 13
Broken: 2.70, 2.70.4
Worked: 2.69

So, simple code, need to apply(press) Set Inverse.

Run Script - go to 3D view - select bone(pose mode) - press "space" - write "constr" - choose "constr" and enjoy or not.

Constraint operators are not really that useful to be called from Python.

For this to work you need to set the constraint in the context...

eg:

  context_py = bpy.context.copy()
  context_py["constraint"] = constraint
  bpy.ops.constraint.childof_set_inverse(context_py, constraint="Child Of", owner='BONE')

This was very hidden, so I have added a message blender/blender@bef1edb322 which now shows:

   Traceback (most recent call last):
     File "/d/child_of2.blend/Text", line 21, in execute
     File "/src/blender/release/scripts/modules/bpy/ops.py", line 188, in __call__
       ret = op_call(self.idname_py(), None, kw)
   RuntimeError: Operator bpy.ops.constraint.childof_set_inverse.poll() Context missing 'constraint'
