 While diting a map with wxdigit, you may accidentally (I mean it's a
 nonsense)
 attemp to remove a vertex to a two-vertices line: digitizer and gui will
 immediately crash. As often in this case the map is damaged, with the
 warning : "Coor files of vector map <mymap> is larger than it
 should be (XXXX bytes excess)"

 After rebuilding the map, the only way to restore it is to purge the
 zero-length segment, then everything runs fine again for your map.

 wxdigit should prevent removing a vertex to a line if it's made of less
 than 3 vertices, or implicitly delete the single remaining vertex.
