Package: python-scipy
Version: 0.6.0-3
Severity: normal

Hello,

when running scipy.test(level=1) with python2.4 or python2.5 it fails
giving an "Illegal instruction" and the interpreter returns with 132.

The output is the following:

If you need more information or want me to run different tests I'll be
happy to help you.
