Using the python debugger is not very useful for segfaults (which happen 
in C code, not python code).

You may want to try running the code under gdb instead.

But I suspect an issue with numpy/scipy imports. You need to use the 
same numpy as the one used when building scipy - recent versions of 
numpy has a safe guard to warn against versions mismatches, but older (< 
1.4) don't have it.

To know for sure which version of numpy you import, you can use:

python -c "import numpy; print numpy.__version__, numpy.__file__"

Make sure this is the same when you build scipy and when you import it 
later.

cheers,
