I just tried it out, but don't see this segfault.

Rudolph, could you maybe do the following:

~> which python

~> gdb the_path_to_python_as_given_by_the_previous_command
[...]
(gdb) run
[...]
>>> import scipy
>>> scipy.test(1, 10)

Then the segfault should bring you back to the debugger.
Then type `bt` for a backtrace which sometimes
gives some more info and post the result here....

Best, Arnd
