Vector menu and Sextante -> ftools behaving inconsistently

Following on from Giovanni's suggestion I'm filing against both Sextante and F-Tools.
In QGIS the two ways of reaching the Geoprocessing -> Intersection tool are giving very different results. Details are below, but since these should give the same result, something is clearly wrong.
Using the following files:
(Note: second file has no projection details, and needs to be set to WGS84)
Using the Vector -> Geoprocessing Tools -> Intersection (point in first field, polygon in second)
Gives an invalid geometry warning, and an empty shape file. (attached VectorIntersction.zip)
Using Sextante -> Ftools -L Geoprocessing Tools -> Intersection (also point in first field, polygon in second)
Gives no warinings and a shape file which is essentially a one to many join. (attached SextanteIntersection.zip)

I'm with this same problem in QGIS 1.8 on Windows 7.
I've tested now with the master version compiled in the last weekend, on Xubuntu 12.04, and the result is similar, with the exception of the processing on Vector -> Geoprocessing Tools -> Intersect, that is not even executed. I leave here a screencast of this test with the master version:
