matplotlib on fc3 crashes


I have tried matplotlib on Fedora Core 3 with the following crash:

Python 2.3.4 (#1, Feb 2 2005, 12:11:53)
Type "copyright", "credits" or "license" for more information.

IPython 0.6.13 -- An enhanced Interactive Python.
? -> Introduction to IPython's features.
%magic -> Information about IPython's 'magic' % functions.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

  Welcome to pylab, a matplotlib-based Python environment.
  For more information, type 'help(pylab)'.

In [1]:from pylab import *
In [2]:t = arange(0.0, 2.0, 0.01)
In [3]:s = sin(2*pi*t)
In [4]:plot(t, s, linewidth=1.0)


exceptions.SystemError Traceback (most recent
call last)

SystemError: Objects/moduleobject.c:48: bad argument to internal function
Segmentation fault

I have the matplotlib-0.84 version, where 'python install' succeded.

Thanks for any help.

PS: Has anyone managed to install the full SciPy on FC3?
