Comment:

 r15815 implements a better solution by going over the epsg code and
 OGRSpatialReferenceH if it is an epsg projection. Like this, the
 projection is recognized better by QGIS.

 For a perfect handling of CRS, the calculator should be ported to the new
 raster provider functions such that calculation can be done on rasters in
 different CRS. This is out of scope for 1.7, so I'm changing version and
 title of the ticket.
