Are you sure that the map is contained in the current region?
ie run 'g.region rast=erode.index' first.
If there is no data to display, NULL (aka very large integer) is passed to the
range-finding routines & it crashes.
It isn't as simple as testing for data at startup, as if you add a second
raster or set a color layer with no data it will crash out as well, which can
be a pain if you've spent some time getting the view right, etc.
Could that be it?? Is there a MASK in place?
