[matplotlib-devel] Embedding a plot in gtk3

Hi,

I'm porting a python application that makes use of matplotlib from
gtk2 to gtk3. However, if I try to embed a matplotlib graph in a gtk3
app I get this:

/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40:
Warning: specified class size for type `PyGtkGenericCellRenderer' is
smaller than the parent type's `GtkCellRenderer' class size
 from gtk import _gtk
/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40:
Warning: g_type_get_qdata: assertion `node != NULL' failed
 from gtk import _gtk
/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40:
Warning: g_ascii_strncasecmp: assertion `s2 != NULL' failed
 from gtk import _gtk
Segmentation fault

Is there any way to embed a plot in gtk3? If not, are there plans to
support gtk3 in the near future?

Thanks and regards,
Fran
