[Gtk-sharp-list] Drop-down list

[Chris Wilson]

You probably need to do something like the following:

groupCombo.Model = groupStore;
CellRendererText cr = new CellRendererText ();
groupCombo.PackStart (cr, true);
groupCombo.AddAttribute (cr, "text", 0);

That should fix the invisible entry issue.
