Also crashes trunk. The view becomes a VERY zoomed in version of the raster. The raster reading algorithm scales the raster many times to achieve the zoom in (0.000008 map unit per pixel). As the entire raster is read into memory, a huge buffer is needed. In fact, almost a Petabyte is needed, a number so big it can't be handled in a 32 bit int.
To fix this, we need to partially read rasters into memory. Or a way to decide if they should be read at all (depending on zoom-level?). Or both?
