Package: python-gi
Version: 3.2.2-1
Severity: serious
On the pygtk page everyone is encouraged to upgrade from pygtk to
using gtkCo through gobject introspection. The further described
behavior introduces a regression compared to pygtk.
You call Py_Initialize(), then import a python script, which contains
at least one(!) of the following imports:
from gi.repository import GLib
from gi.repository import Gtk
from gi.repository import Cairo
from gi.repository import Pango
from gi.repository import Gio
Than you call Py_Finalize();
After you repeat Py_Initialize() and try to import the script again,
it segfaults.
But there is no problems with pygtk.
Please try out this small program and if it fails for you, please
confirm the bug upstream:
https://bugzilla.gnome.org/show_bug.cgi?id=677091.
Thanks,
Andrey
