Hi,
I had fun writing a basic MAT nautilus extension. It works fine for me
under Tails, with nautilus 2.x.
For now, it doesn't work with nautilus 3.x under wheezy. If I understood
the problem well, Nautilus 3.x imports Gtk through GI, while poppler and
cairo (imported by MAT) import Gtk2 through python bindings. Result:
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
import gobject._gobject
/usr/lib/python2.7/dist-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/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed
from gtk import _gtk
Segmentation fault
Cheers,
Alan
