if you run the process from the command line

gdal_polygonize.py /home/giovanni/Desktop/Raster1 -f "ESRI Shapefile" /home/giovanni/Desktop/lixo/test.shp test DN

you will notice that it is gdal_polygonize.py that created the output with such CRS, QGIS in this case it is just an interface.

The ticket should be filed in the gdal/ogr bug tracker.

Cheers!

But I run it from the Rastermenu. And here it gives this result. Has you transfered the bug to gdal/ogr?

all the tools formerly known as "gdal tools" are GUIs for the gdal utilities
