it happens also on Debian:

$ python
Python 2.7.2+ (default, Oct  5 2011, 10:41:47)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.use('GTKAgg')
>>> from matplotlib import pyplot as plt
>>> plt.plot((1,2), (2,4))
[<matplotlib.lines.Line2D object at 0x2f7e6d0>]
>>> plt.show()
/usr/lib/pymodules/python2.7/matplotlib/backends/backend_gtk.py:552:
GtkWarning: IA__gtk_widget_unrealize: assertion `GTK_IS_WIDGET
(widget)' failed
  self.toolbar.destroy()
/usr/lib/pymodules/python2.7/matplotlib/backends/backend_gtk.py:552:
GtkWarning: IA__gtk_widget_is_toplevel: assertion `GTK_IS_WIDGET
(widget)' failed
  self.toolbar.destroy()
Segmentation fault
