Here's the output for my dummy script. I'm using pylab functions: show,
figure and bar, though just importing pylab without actually using the
functions produces the same problems, that's why at first I thought the
problem is related with something in the import.

I've tried with just these imports and there's no problem with that,
everything runs ok, it's when I add the pylab imports when everything
goes wrong. I've tried with these three posibilities and the result is
always the same:
import pylab
from pylab import *
from pylab import figure, show, bar
