The cause seems almost certainly to be in the atlas libs rather than scipy per se: Scipy will load the atlas versions of the lapack/blas libs if available, but if not falls back to lapack3/refblas3.
Warty has atlas 3.6.0-13, and does not have the problem, dapper has atlas 3.6.0.20 and does. The problem can be made come and go simply by installing/removing atlas, which does affect any other packages. This holds true for i686 and x86_64.
