[Python-Dev] Possible bug in randint when importing pylab?

I am getting some unexpected behavior in Python 2.6.4 on a WinXP SP3 box.

If I run the following:

[code]
from pylab import randint

for s in range(100):
    print randint(0,1)
[/code]

I get 100 zeroes.

If I import randint from random instead, I get the expected behavior
of a random distribution of 1s and 0s.

I found this by importing * from pylab after importing randint from random.

What is going on? Is pylab's randint function broken somehow? Could
this be due to installing scipy into a 2.6 environment when it was
designed for the 2.5 environment?
