Crash when using MTScatter

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run software that does these things: 
w = MTWallpaperWindow(wallpaper='wallpaper.png', fullscreen=False)
    k = MTKinetic()
...
self.mtobject = MTScatterImage(filename=self.imgpath) 
k.add_widget(self.mtobject)
(in objects - so several of these added)
...
k.process_kinetic()
    w.add_widget(k)
    runTouchApp()

2. Run the app.
3. Play around with the items on the screen for a while using a multi-touch 
surface.

What is the expected output? What do you see instead?
Expected output - being able to continue to work with the items on screen

Thank for reporting, it's a known bug, but missing in issue list.
This happen when you move too close 2 points on a scatter widget.
(open a point with right click, and move a second point near the first... and 
crash.)
