Just reply in the normal way and it will go to the list so everyone can see
it. To open a ticket, go to the scipy site <http://www.scipy.org/> and click
on the report bugs icon and follow instructions. You will need to register
and it will help if you can produce a simple example the reproduces the
problem. I used powers of two for the dimensions because these sort of
problems tend to be related to counting in binary. Ones instead of random
makes the arithmetic exact so it is easier to see what is going on, etc.
