Hello,


I'm trying to use Gary's receipt (thanks Gary, and sorry for answering 
so slowly :-( but I get the following error (as can be seen running the 
attached script):

Traceback (most recent call last):
  File "finder.py", line 13, in ?
    measurements.find_objects(label_matrix)
  
File "/usr/local/lib/python2.4/site-packages/scipy/ndimage/measurements.py", 
line 89, in find_objects
    return _nd_image.find_objects(input, max_label)
RuntimeError: data type not supported


It seems to be a bug. Am I right? Or am I doing something stupid?

Thanks in advance for your help.
