 * import (-o) the .asc file from
 https://www.dropbox.com/s/w60ywwddl3aj03h/cavallini.zip
 * r.to.vect
 (you can see the results of these operations in the location, in the zip
 above)

 Display raster and vector, either in GRASS or in QGIS (in this second you
 can also load the original raster).

 Results: the original raster and the derived vector align perfectly, the
 imported raster shows shifts while zooming in and out. See attached
 screenshots as an example.

 Additionally, in qgis-dev I get errors querying the raster:
 168 bytes expected but 3200000 byte were read from qgis.d.rast

 Tested on 3 different machines (Debian Unstable, Ubuntu, Windows).
