Comment (by leolami):

 Hi all,
 the problem seems solved, I tested using a projection like Gauss Boaga
 standard (EPSG code=3003)

 +proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl
 +units=m +no_defs

 I try to reproject with a UTM wgs84 fuse 32N layer and it works well.

 A little correlate problem is that if I load a layer from a Location of
 GRASS with this parameters of projection:

 +proj=tmerc +lat_0=0 +lon_0=9 +k=0.999600 +x_0=1500000 +y_0=0
 +ellps=intl +units=m +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68

 when I look the projection associated to this layer I can see that QGIS
 doesn't know this projection and that it associates to the layer the
 projection setted as default.

 But if I create a custom projection like this and I set it as the default
 projection  when I load the GRASS layer I see that QGIS associates to the
 layer the standard projection:

 +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs

 but I remember that before QGIS readed the projection with parameters like
 the same projection withot them and it associated to the layer the
 standard Gauss Boaga projection (EPSG code=3003)

 Do you think we have to reopen the ticket?

 Thank you
 Leonardo
