Bug report #15793

Qgis 2.18 32bit osgeo network installer Win 10.
If you have a polygon with a ring, when you use fill ring tool, you obtain a new geometry (as you expect) and a new part of the previous geometry.
Example:
in a shapefile
1 - add a polygon
2 - save it
3 - add a ring
4 - save
5 - fill it with fill ring
Result
- a new geometry added inside the shape of the ring
- a new "multipart" added without a correct shape
Also in spatialite the same, but it doesn't allow to save, and, if you discard the editing, the feature will be saved with a new unformed multipart.
If you try to delete the new multipart, all the geometry will be deleted.
