I tried hard but cannot reproduce your error in Grass 6.1 (CVS 13.08.05) on
Linux. Can you?

However, I noticed something related:

1. zoom into an area
2. create a raster encopasing the region e.g. 'r.mapcalc map=1'
3. change the region so that your 'map' falls completely outside of it
4. create a MASK, eg. 'r.mapcalc MASK=1'
5. g.region rast=map; nviz elev=map
6. segfault:

Loading Data
Update elev null mask
Error finding range
building color table
Error finding range
recalculating normals...
% Segmentation fault

Maybe that is what you enountered? But no vector files involved...


Although it is quite ulikely someone would like to run NVIZ on a raster which
is masked out, but could such situation be handled more gracefully for the user?
