For me, QGIS sets CRS to raster's CRS but some info seems to be lost
in createFromWkt().

GRASS gives: GEOGCS["wgs84",DATUM["WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563],TOWGS84[0.000,0.000,0.000]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]]

QgsCoordinateReferenceSystem.createFromWkt().toWkt() gives:
GEOGCS["WGS 84",DATUM["unknown",SPHEROID["WGS84",6378137,298.257223563],TOWGS84[0,0,0,0,0,0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]]

QgsCoordinateReferenceSystem.authid(): EPSG:4148
QgsCoordinateReferenceSystem.description(): Hartebeesthoek94

Everything for CRS QgsCoordinateReferenceSystem created from WKT given
by GRASS above.

Here I am only QgsCoordinateReferenceSystem user, can anybody knowing
QgsCoordinateReferenceSystem explain what is happening and what is
wrong? I have added more debug output, you can grep everything
importing with grep -i crs.

Region should be reprojected of course, but that has nothing to do
with rasters, please fill a ticket for GRASS plugin.
