Comment (by usovalx):

 I still can't make it work for the provided example (where array shape is
 3x1000x1000).
 Importing scipy explicitly  doesn't seem to change anything (it's fedora
 8,
 scipy-0.6.0-3.fc8 package).

 For arrays of 512x512x200 it seems to work (at least it produces some
 results
 without crash), but I can't easily check correctness of the extracted
 objects.
 For some of mine tests I did previously, I saw completely broken labeling
 coming out.

 I just did few more tests with smaller array sizes, and it seems like it
 works more or less
 fine while 2d part of the array is reasonably small, and breaks when it
 get bigger then 1Kx1K.
 Funny fact -- array shape 1Kx1Kx3 works fine, while 3x1Kx1K crashes it :)
