G only is a record and the numbers in it (14, 15, 16) are handles to
ets tables containing the graph data. These are owned by the shell
process and disappear when that process crashes and dies. When calling
digraph:info/1 again, it queries the inexistent tables for their size
and they return "undefined" instead of a size and there's a badarith
exception when trying to add those 'undefined' atoms...
A better error message would be very useful in this case, I think.
