 Hi all! It's Kiara. I am using a script to overlay two shapefiles,
 respectively line and polygon type. The overlay operation gets stuck at
 approximately 74%, and it happens in the script, by command line and also
 by using the grass toolbox in qgis. maybe the problem is the number of
 vertices?
 More info: (ALL_ROUTES_M1SO6 is the line map, prova_conc_grand_grass is a
 test polygon i'm using)

 *** here I stopped the procedure, and after that I cannot open the map
 that has been created. My maximum wall time has been 20 minutes...is that
 normal?

 thanks a lot
 Kiara
