[SciPy-user] bug in scipy array?

hi,
i came across the following strange behavior while multiplying a
scipy array:
a[:,2:] gives a column of zeros if a is an 2x2 array (that is correct)
but if i multiply this column by zero, it affects the element a[2,0]
which is probably a bug.
>>> from scipy import *
>>> a = array([[1,2],[3,4]])
>>> a
array([[1, 2],
[3, 4]])
>>> a[:,2:]
zeros((2, 0), 'l')
>>> a[:,2:] *= 0
>>> a
array([[1, 2],
[0, 4]])
i am using scipy 0.3.2 with python 2.4.2 and Mac OSX 10.4.5.
thanks for any help/comment.
