Hummm, i found that the minscale mapscale used to draw the map is the 
reason of the error.

How can i know the good value to put in minscale, maxscale for having a 
correct behavior at the scalebar ?
for example :
Before with 65 at the top scale we have a graduation  in meters ( +/- 0 
to 80 )
Now with  65.000.000 at the top scale we have a graduation in kilometers 
( 0 to 4500)

How know how to set this value correctly ?
