Public bug reported:
Binary package hint: python2.6
Simple instruction: fire up python, then on the prompt type:
import scipy.linalg
Python crashes. Upon examination in GDB, I found the following:

Clearly it tried to call a NULL subroutine. The scipy version is:
0.7.0-2ubuntu0.1 . BTW I also have lucid installed on a x86-64 laptop
and it did not have this problem.
