What version of pygtk are you running? matplotlib requires 1.99.16.
don't know about Mandrake, but Redhat 9 comes with 1.99.14, so it is
possible you don't have a recent enough version of pygtk. If you
would be willing to install pygtk-2.0.0 (it's just a 'python setup.py
install') and let me know if you can run the simple_plot.py example
from the command line, and then let me know if the crash goes away in
pycrust and Boaconstructor.

This is the way to select among various backends (PS, GD, GTK, WX)
that the matlab module uses. It can only use one, so you have to
select it before you import the matplotlib.matlab module.
