Just got a crash just summing up 2 rasters with rastercalc with qgis-trunk: Error: GDAL Error 5: Access window out of range in RasterIO(). Requested (0,299) of size 300x2 on raster of 300x300. Segmentation fault If necessary, I can send the rasters. All the best. -- Paolo Cavallini: http://www.faunalia.it/pc
