 (This bug may be related to #1943 and also to #1889, if it isn't even the
 same.)

 Im working with crs epsg 21781. If I create a new shapefile with the "new
 vecotr layer" tool, the shapefile is missing the towgs84 part in its crs
 parameters.

  1. Open Qgis
  2. in project properties set tht crs to epsg 21781/CH1903 (Enable 'on the
 fly' is also set).
  3. in the settings->options->crs set "project wide default crs will be
 used"
  4. with the "new vector layer"-button create a new shapefile and save it.
  5. load the created shapefile into qgis
  6. open the properties of the new shapefile
  -> the crs of the shapefile is missing the towgs84 parameter and
 therefore it displays on a wrong place in the canvas.

 I attach the debug output from the console when creating a new shapefile
 in this way. You will see that from line 1 to 14 all output concering crs
 has the towgs84 information. As from line 41 on the towgs84 part is
 missing. So it seems to be a problem of the qgsvectorprovider or ogr.

 The crs in the srs.db is ok, also the epsg file of proj.
 Currently I'm running r12143.

 regards
 Cedric
