Pygame segmentation error when using SimpleCV findBlob library

Question

I use SimpleCV to find drops that can be used with a self-driving robot. The problem is that I call the findBlobs command in SimpleCV. When I completely lock the Kinect camera lens, a PyGame crash gives me this error:

Fatal Python error: (pygame parachute) Segmentation error

Sometimes it works, and sometimes it just falls, even when the lens is unlocked. It will almost always crash when I run it for longer than thirty seconds. I reinstalled and fixed many problems in SimpleCV and tried reinstalling Pygame, and it doesn't seem to help at all. In addition, I use the Kinect X-Box as the source of the camera. I am using Ubuntu 11.04.

Here is my exact code:

from SimpleCV import *
from SimpleCV.Display import *
from time import sleep
k = Kinect()
dis = Display()

while 1:
    depth = k.getDepth()
    depth = depth.invert()
    depth = depth.erode()
    blobs = depth.findBlobs(threshval=127, minsize=10, maxsize=0)
    if blobs:
        blobs.draw()
    depth.save(dis)
    sleep(0)
