[Paraview] python scripting inside Paraview

If I run the following script, Paraview crashes to the console with the
error:
terminate called after throwing an instance of 'std::bad_alloc'
what(): St9bad_alloc
Aborted
As I said if I remove the line
disp = paraview.CreateDisplay(line, activeView)
the script will complete correctly, but I would have to manual turn on each
element
something that I want the script to do
#!/usr/bin/env python
import paraview
# Locate the view to which we'll add the "display". All views are
# registered in the group "view_modules" with the proxy manager.
pxm = paraview.pyProxyManager()
iter = pxm.group_iter("view_modules");
activeView = None
for proxy in iter:
if proxy.IsA("vtkSMRenderModuleProxy"):
activeView = proxy
break
if activeView:
for z in range (0, 10):
for y in range (0, 10):
for cc in range (0, 10):
# create a display for the source in the active view.
line = paraview.CreateProxy("sources","LineSource","sources",
"line.%d.%d.%d"%(cc,y,z))
print cc, " ", y, " ", z
line.SetPoint1(cc,y,z)
line.SetPoint2(0,0,0)
line.UpdateVTKObjects();
disp = paraview.CreateDisplay(line, activeView);
activeView.StillRender();
