Can you give a pointer to the mail describing this problem ?

It looks a lot like the problem we had some time ago with python: objects  
can't be transfered to one .so module to another .so module. Just to be  
sure, can you replace your SmoothingRecursiveGaussianImageFilter by a  
ImageFileWriter ?
