matplotlib 1.1.0 Segmentation fault

Hi, since the update yesterday:

Code: Select all

$ python
Python 2.7.2 (default, Dec  3 2011, 10:29:45)
[GCC 4.6.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import  matplotlib.pyplot as plt
>>> plt.figure()
<matplotlib.figure.Figure object at 0x301cf90>
>>> plt.show()
/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_gtk.py:552: GtkWarning: IA__gtk_widget_unrealize: assertion `GTK_IS_WIDGET (widget)' failed
  self.toolbar.destroy()
/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_gtk.py:552: GtkWarning: IA__gtk_widget_is_toplevel: assertion `GTK_IS_WIDGET (widget)' failed

Segmentation fault


I ermerged the old version:

Code: Select all

emerge -av =matplotlib-1.0.1-r1


and all works fine.
