isolatedConnect.py crashes the whole of DeVIDE in certain seedpoint configs

[GoogleCodeExporter]

(reproducer submitted by Christian Vermorken, thanks!)

load up the attached DVN file. Delete points from the slice3dVWR, then try to 
add one point and see DeVIDE 12.2.7 crash.

This is due to ITK's IsolatedConnectImageFilter throwing its toys out of the 
cot after a certain sequence of ClearSeeds() / AddSeed() calls. Disappointing.

I've narrowed it down some more. Run the attached network to prime the 
IsolatedConnectedImageFilter in the CodeRunner with some volume input. Then do 
the following to reproduce the crash:

{{{
icf.SetSeed1(itk.Index[3]([0,0,0]))
icf.Update()
}}}

So it seems to be a relatively simple case of the IsolatedConnectedImageFilter 
crashing when one of its seed lists is empty.

Doing the following also causes a crash:

{{{
icf.SetSeed1(itk.Index[3]([0,0,0]))
icf.SetSeed2(itk.Index[3]([1,1,1]))
icf.Update() # NO CRASH YET
icf.ClearSeeds2()
icf.Update() # CRASH!
}}}
