Loading the raster map within NVIZ it doesn't crash but doesn't display
anything. However, it says:
"shine set to: 76.000000
Color Material: 4609
"

Here is (from global dataset):

------------------------------------------------

Aha "funny":
- it crashes if the map region contains only NULL data values (should
  gracefully exit here). Above happened when I was (accidentally) working
  in a NULL data area in "nations" map.

Maybe that's another bug. Helena, are you sure that your map contains data
when crashing with NVIZ?
