 It is possible to set a routine which handles GRASS errors with
 G_set_error_routine. The problem is, that both QGIS GRASS plugin and GDAL
 GRASS driver do it. GDAL sets Grass2CPLErrorHook while GRASS
 QgsGrass::error_routine. When an error happens in GDAL it does not call
 the Grass2CPLErrorHook but QgsGrass::error_routine because the routine was
 reset in the mean time by QGIS GRASS plugin. QgsGrass::error_routine
 throws QgsGrass::Exception but that is not caught by raster layer renderer
 (right, it is expecting error from GDAL) and thus qgis crashes. Isn't it
 nice!?

 This was discovered when fixing #1900
