New submission from Narnie Harshoe <signupnar...@gmail.com>:
Using the following code for a Gtk.CellRenderSpin results in the following
error after changing the spin button several times.
The error is:
/usr/lib/python2.7/dist-packages/gi/types.py:43: Warning: g_object_notify:
assertion `G_IS_OBJECT (object)' failed
return info.invoke(*args, **kwargs)
Segmentation fault

from gi.repository import Gtk
class CellRendererSpinWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="CellRendererSpin Example")

self.liststore = Gtk.ListStore(str, int)
self.liststore.append(["Oranges", 5])
self.liststore.append(["Apples", 4])
self.liststore.append(["Bananas", 2])
treeview = Gtk.TreeView(model=self.liststore)
renderer_text = Gtk.CellRendererText()
column_text = Gtk.TreeViewColumn("Fruit", renderer_text, text=0)
treeview.append_column(column_text)
renderer_spin = Gtk.CellRendererSpin()
renderer_spin.connect("edited", self.on_amount_edited)
renderer_spin.set_property("editable", True)

renderer_spin.set_property("adjustment", adjustment)

win.show_all()
Gtk.main()
This code comes from

My system is a Debian system tracking debian testing.
Exact python --version is Python 2.7.2+
