 Using r15215 under Ubuntu.

 I think I found some kind of raster that causes QGIS to crash when the
 project CRS is not equal to the raster crs.

 [Note1: Yes, I know that QGIS can't reproject rasters, but I guess that
 this kind of crashes should be avoided.]

 [Note2: I don't see the same happen with the rasters in the qgis sample
 data set]

 Example:

 *) pick the attached raster, it is a geotiff defined in epsg:3763

 *) set the project CRS as wgs84, epsg:4326

 *) the raster obviously disappear from the canvas.

 *) try zooming to the layer and/or changing the zoom level with the mouse
 wheel: QGIS starts eating memory and after a few seconds it crashes. Seg
 Fault.

 *) I found other similar rasters that cause instant crash when the project
 crs is set to wgs84 and the user try to zoom to the layer


 If it warp the same sample raster in wgs84 and I try the other way
 (project in epsg:3763) qgis does not crash.


 I tested also r15223 with same results.
