python coredump when using GtkAgg mode

_assiss · August 18, 2006, 6:53am

hi all,
I installed matplotlib and it worked very well with TkAgg/Agg. But when use GtkAgg or Gtk, python just coredumped without any prompts.
For example, python a.py -dTkAgg, it worked. python a.py -dGtkAgg, “Segmentation fault (core dumped)”.

When running the examples with -dGtkAgg, gtk_spreadsheet.py embedding_in_gtk.py embedding_in_gtk3.py worked, embedding_in_gtk2.py pylab_with_gtk.py failed and coredumped without any prompts.

My system is NetBSD AMD64-3.0. With python 2.4.3, gtk±2.8.19, pygtk-2.8.6.

Is there someting wrong with my system? Thanks for your suggestion.

Since your error was with gtk try:

import matplotlib.backends._gtkagg

I am guessing that will fail. You might try reinstalling gtk and
pygtk. I doubt anyone has NetBSD to confirm your error though.
