Hi Hamish,

Ok, I see, I thought that this error message was also linked to the fact 
that my map is distorted and that I couldn't draw a grid.

For the grid I'm fine now, my error was that the units for the gridlines 
are not in degrees, but in rad or something like that.

But my graph is twice much larger than I expected it (and looks quite 
ugly), but probably it's due to the fact that Grass takes the same 
distance for 1degree in NS and EW in LongLat.
It seams also impossible to draw a North arrow and a scale in LongLat.
