 When buffering a shapefile that has epsg 21781 (CH1903) with ftools
 buffer, the resulting shapefile is lacking the towgs84 parameter in the
 crs (and the prj-file) and is therefore misplaced.

 This seems to be similar to Ticket #1889, but this time is not the
 creation of a new shapefile affected but the buffer.

  1. load attached shapefile
  2. buffer with ftools and buffer distance of 50 meters
  3. load the resulting shapefile
  [[BR]]
 => shapefile is misplaced due to missing the towgs84 parameter in the
 projection
