While using LGI based bindings (Lua), creating cells with duplicate names will trigger a crash during destruction. Test case follows:

local lgi =     require 'lgi'
local Adg = lgi.require 'Adg'

local t = Adg.Table()
local r = Adg.TableRow(t)

Adg.TableCell.new_full(r, 1, 'duplicate name')
Adg.TableCell.new_full(r, 1, 'duplicate name')

This will give a Segmentation fault (core dumped) at the end of its execution (or, better, it is what I get on a couple of systems).
