I think you are wrong here. It does match with the signature of the
second add_attribute variant:
void Gtk::TreeViewColumn::add_attribute (
const Glib::PropertyProxy_Base& property,
const TreeModelColumnBase& column)

You pack only one cellrenderer in the column and use one of the other
"add_attribute" functions, but for the rest the code is the same as mine
(I checked and your variant has the same problem, even with only one
cellrenderer). You are right when you say the toggle renderer can be
checked or unchecked (by changing the boolean value in the underlying
model through code). But I can't modify that value through the user
interface!
If I simply do:
m_treeview->append_column_editable ("Active", m_columns.active);
m_treeview->append_column ("Name", m_columns.name);
the values can be changed through the user interface as expected. But
this creates two separate columns (see screenshot [1]), but I only want
one (see screenshot [2]).

CellRendererToggle does not have a 'property_editable'. That property is
for use with CellRendererText.

I'm using packages from Ubuntu Feisty:
$pkg-config --modversion gtkmm-2.4 gtk+-2.0
